EECS16A, Designing Information Devices and Systems I

Fall 2023


Course Info

The EECS 16AB series (Designing Information Devices and Systems) is a pair of introductory-level courses introducing students to EECS. The courses have a particular emphasis on how to build and understand systems interacting with the world from an informational point of view. Mathematical modeling is an important theme throughout these courses, and students will learn many conceptual tools along the way. These concepts are rooted in specific application domains. Students should understand why they are learning something.

An important part of being a successful engineer is being able to identify the important and relevant structure in a complex problem while ignoring minor issues. EECS 16A focuses on modeling as abstraction: how can we see the relevant underlying structure in a problem? It introduces the basics of linear modeling, largely from a "static" and deterministic point of view. EECS 16B deepens the understanding of linear modeling and introduces dynamics and control, along with additional applications. Finally, CS 70, (which can be thought of as the third course in this sequence --- except without any labs), introduces additional discrete structures for modeling problems, and brings in probability.

In EECS 16A in particular, we will use the application domains of imaging and tomography, smartphones and touchscreens, and GPS and localization to motivate and inspire. Along the way, we will learn the basics of linear algebra and, more importantly, the linear-algebraic way of looking at the world. The emphasis will be on modeling and using linear structures to solve problems; the class is not just focused on how to do computations. We will learn about linear circuits, not merely as a powerful and creative way to help connect the physical world to what we can process computationally, but also as an exemplar of linearity and as a vehicle for learning how to do design. Circuits also provide a concrete setting in which to learn the key concept of "equivalence" --- an important aspect of abstraction. Our hope is that the concepts you learn in EECS 16A will help you as you tackle more advanced courses and will help form a solid conceptual framework that will help you learn throughout your career.

Grade Breakdown

Our objective is to help you become the best engineer you can be, and grades are not everything. The various components of the class -- homework, labs and exams -- are designed explicitly with this in mind. Every challenge is a growth opportunity. You will have the opportunity to gain points in the course through completing your homework and attending labs as well as through the exams. We will periodically update Status Check (will be linked here soon) with your grades throughout the semester so you can keep track of your grades in the course and identify any grading issues.

This course is not graded on a curve. We will set absolute thresholds for performance that will map to grade boundaries. We encourage you to discuss the course material with each other and teach each other new ideas and concepts that you learn. Teaching the material is one of the best ways to learn, so discussing course material with colleagues in the class is a win-win situation for everyone. Grades are not everything, far from it, but that said, here is the breakdown for grading for this class:

If you opt-in for discussion participation
Category Points (out of 300)
Discussion Participation 12 points
Homework 45 points
Labs 45 points
Midterm 1 50 points
Midterm 2 50 points
Final 98 points
If you opt-out for discussion participation
Category Points (out of 300)
Homework 45 points
Labs 45 points
Midterm 1 54 points
Midterm 2 54 points
Final 102 points

See the section “Participation in Discussion” to learn more about opting-in versus opting-out of discussion participation. Also, notice that you can get many points by being regular with your homework and the labs. Our goal is to help you learn the material as best as possible!

Grading Scale

This course is not curved. We define the following grading scale (in percentages):

A [93+) A- [90+)
B+ [84+) B [75+) B- [68+)
C+ [65+) C [62+) C- [58+)
D+ [57+) D [55+) D- [53+)
F [0-, 53)

Exam Clobber Policy

This course spans a fairly broad set of ideas and concepts within a short period of time, and hence sustained and consistent effort and investment are critical to your success in this class. Similarly, by far the most common operating mode we have observed in previous students who struggled and/or failed this class was attempting to do the bare minimum in general and then catch up/cram right before the exams.

To give students a ‘second chance’, we will provide the opportunity to clobber a midterm to students who complete an optional midterm redo. If you do not complete the midterm redo, you will not qualify for the clobber.

For each midterm, if you complete the midterm redo, we will replace your corresponding midterm score with 85% of your final exam score if it would help your grade. We will use the following formula:

clobbered midterm score = max(original midterm score, 0.85 * score on final exam)

For example, if opt-in to discussions, and you score 50% on the first midterm (0.5*50 = 25 points) and 80% on the final, then you midterm 1 score will be instead set to (0.8*0.85)*50 = 34 points (as opposed to getting a 25).

Homework (HW) Party and Office Hours (OH)

Homework parties are your chance to meet and interact with other students, while also having the chance to get help from GSIs, tutors, and faculty. We expect students to treat each other with respect during homework parties as well as during all other parts of the class, including interactions on Ed, discussion, and office hours. Remember that each of you is coming into a class with different experiences and backgrounds -- use this as an opportunity to learn from one another.

Wednesdays 9-11AM and Fridays 9-11AM, HW Party will be held in Wozniak Lounge (430-438 Soda Hall). Attending homework party is highly encouraged and is a great way to find a study group! Students are expected to help each other out, and if desired, form ad-hoc "pickup" homework groups in the style of a pickup basketball game.

Office Hours will be held almost every day, as annotated on the course Google calendar. You can come to office hours with your study groups, or by yourself -- there will be one or more TAs there to help you work through the concepts or the homework! All office hours will be held in-person in Cory 144MA.

Please note that all course-related questions are welcome at both homework parties and office hours!

Homework and Self-Grade Submission

To receive any credit for homework, you must follow all of the below steps.

  1. Do the homework.
  2. Submit the homework by Friday night at 11:00 PM Pacific Time. We will accept submissions for full credit as long as your submission makes it into Gradescope before the late deadline of 12:00 AM. Submissions on or after 12:00 AM will not be accepted. We strongly recommend you use this one hour grace period to protect against technical issues and have your homework finished by 11:00 PM.
  3. Read the solutions. Official solutions will be released after the homework submission deadline.
  4. Do the self-grade. Grade your submitted work accordingly for every part of every problem in the homework on a simple coarse scale as described in the table below. Enter your self-grades into the posted self-grade form for that homework, which will generate a .txt file, and upload that .txt file to the appropriate self-grade assignment on Gradescope.

    Score Reason
    0 Didn't attempt or very wrong
    2 Got started and made some progress, but went off in the wrong direction or with no clear direction
    5 Right direction and got half-way there
    8 Mostly right but a minor thing missing or wrong
    10 100% correct

    Note: You must justify self-grades of 2, 5 or 8 with a comment. Grades of 0 and 10 do not need to be justified (you can just write "Incorrect" or "Correct"). If you are really confused about how to grade a particular problem, you should post on Ed. This is not supposed to be a stressful process.

    Just like we encourage you to use a study group for doing your homework, we strongly encourage you to have others help you in grading your assignments while you help grade theirs.

  5. Submit the self-grade by the Monday night following the homework deadline at 11:00 PM Pacific Time. (For example: Homework 2 is due on Friday 9/15 at 11:00 PM. The following Monday, 9/18, at 11:00 PM, your Homework 2 self-grades will be due.) We will accept submissions for full credit as long as your submission makes it into Gradescope before the late deadline of 12:00 AM. We will accept late self-grades up to a week after the original homework deadline for 75% credit on the associated homework assignment. If you don't enter a proper self-grade after one week, you are giving yourself a zero on that assignment.

In summary, you must do the homework, turn it in on time, read the solutions, do the self-grade, and turn it in on time. Unless all of these steps are done, you will get a zero for that assignment.

Self-Grade Walkthrough

Reader Grades

Course readers are going to be grading and sending you occasional comments. Your own scores will be used in computing your final grade for the course, adjusted by taking into account reader scores so that everyone is fairly graded effectively on the same scale. For example, if we notice that you tend to give yourself 5s on questions where readers looking at your homeworks tend to give you 8s, we will apply an upward correction to adjust. Any consistent discrepancy between your self-assigned grades and the reader grades will be flagged and checked for academic dishonesty, so please grade yourself appropriately without attempting to inflate your grades. This correction factor, called the reader adjustment factor, will be visible to you throughout the semester on Status Check.

Each week, course readers will grade some (not necessarily strict) subset of the problems. These grades and comments serve as an opportunity to receive feedback on the work you’re submitting over the course of the semester. Reader grades will be released on Gradescope about one week after the homework deadline. Homework regrade requests are typically due on Gradescope within 72 hours of reader grades being released. If a regrade request is submitted for a part of a question on the homework, the grader reserves the right to regrade the entire homework and could potentially take points off.

Homework Effort Policy

Because the point of homework in this class is again to help you learn, not to punish you for making small mistakes, if your final score on any homework is above 8/10, your grade will automatically be bumped up to 100% (10/10). If your final score is less than 8/10, it will be scaled accordingly so that a 6/10 will result in 75% (7.5/10).

Homework Scoring

The following formula summarizes how homework scores are calculated:

We will automatically drop the lowest homework score from your final grade calculation. If you use this drop half-way into the semester, and request another, we cannot help you. EECS47D students will not have their lowest homework score dropped.

Participation in Discussion

Discussion is a key component to learning the material in this class, and to keep you motivated and on track, you can opt-in to discussion participation and earn points towards your grade by attending discussion. Every week, discussion will be held on Monday and Wednesday. Different material will be covered on Monday and Wednesday, so you are encouraged to attend on both days. You may choose to attend any discussion section time on a given day, and are encouraged to try out different TAs’ discussion sections to find which one works best for you. Discussion sections will take place in-person.

At the beginning of the semester, you will fill out a form indicating whether you’d like to opt-in or opt-out of discussion participation. This form is binding, and you may not change your preference later on in the semester. If you opt-in for discussion participation, you will receive credit for attending discussion sections, and it will count as a category of your grade. If you opt-out of discussion participation, discussion attendance will not be factored into your grade. The purpose of this policy is to recognize and acknowledge the efforts of students who continue to invest time in the course throughout the semester. Regardless of whether it counts towards your grade, we highly encourage you to attend discussion sections, as a big part of your learning will be done in this interactive, classroom setting.

For students who opted-in for discussion participation: Discussion participation is worth a maximum of 12 points. This is measured by discussion attendance. For each discussion section that you attend, you will fill out an attendance form to count your participation. You must attend 16 discussion sections to get full participation points. Please note that this number is the minimum required for full credit, but you are highly encouraged to attend more discussions. If you do not get full credit, your grade will be calculated by the number of discussion checkoffs you complete; e.g., if you attend 14 discussions or complete 14 checkoffs, you will have 14/16 * 12 points in this category.

For students who opted-out of discussion participation: You will not earn any credit for attending discussion sections, and discussion participation will not be a part of your final grade. However, this does not mean you are not allowed to come to discussion sections. Discussion sections are open to everyone, and we highly encourage you to come to discussions as much as you can. It complements the other components of this course and will enhance your overall learning experience.

Discussion sections are a great way to apply concepts taught in lecture to practice problems, interact with enthusiastic and dedicated TAs, and collaborate with peers in a smaller group setting. It’s a great way to meet other students in the course, and we notice that students who regularly attend discussions find the homeworks and exams more easy and manageable.

The form (linked here)for indicating whether you opt-in or opt-out of discussion participation is due by Friday, September 15th at 11:00 PM Pacific Time. This gives you the opportunity to try out discussion sections for the first couple of weeks before deciding, as you may not change your decision later on. We will be tracking attendance starting from 8/28, so make sure to fill out the attendance form for every discussion you attend from then on (unless you are 100% sure you want to opt-out). Again, please fill out the form by the deadline and make your decision carefully; your decision is binding. If you do not fill it out, we will assume that you are opting-out.

Lab Policies

Labs this semester will be held in-person, except where otherwise stated on Ed. Labs for this class are not open section, you must go to your assigned lab section.

Credit for each lab is based on completion and checkoff with a member of lab staff during your assigned lab section. In a checkoff, you will demonstrate your work from portions of the lab and answer conceptual questions related to the lab. You should aim to get checked off by the end of your lab section. If (and only if) you attend your lab section for the whole duration but do not finish in time, you may get checked off at the beginning of your next lab section before starting the following lab. We have the following grading policy for labs: If you complete all the labs, you will receive full lab credit. If you fail to complete one lab, you will receive almost full 44/45 lab credit. If you miss two labs, you will receive 42/45. If you miss three labs, you will receive 23/45 (half credit). If you miss four or more labs, you will get an F in the class.

Number of Missed Labs What Happens?
0 You get full lab credit - 45/45
1 You get almost full lab credit - 44/45
2 You get most lab credit - 42/45
3 You get half lab credit - 23/45
4 or more You Fail the class - final letter grade: F

Some lab sections are “buffer labs”. These are held during a week-long period at the end of each lab module in which no new labs begin.

You may get checked off for only one missed lab per lab module by attending a buffer lab for that module. No other labs can be checked off. If you have already completed all labs for a particular lab module, you do not need to attend a buffer lab for that module.

Students must sign up for a buffer lab before attending. Please note that not all regularly scheduled lab sections will be run as buffer lab sections. Further details will be shared duly on Ed.

Wires on lab breadboards must be planar. All students will receive a lab kit to use during lab sections. Lab staff will ask students to redo their circuits before debugging them if the wires are non-planar. The definition of planar wires on a breadboard is shown below:

Planar Non-planar

Exam Policies

There are two midterms and one final. All exams will be held in-person. The midterms will be held in-class during the regular lecture time from 9:30am to 11:00am PT in Wheeler 150. The first midterm will be held on Tuesday October 3, and the second midterm will be held on Thursday November 9. The final will be held on Tuesday, Dec 12th, from 3:00pm to 6:00pm PT.

Makeup exams will not be scheduled. Alternate exam times will not be provided under any circumstances, except for students requiring specific DSP accommodations. Please contact us privately if you have any concerns.

Please plan for exams at these times. In case of an emergency on exam day, please email the Head GSI at as soon as possible and provide details of the issue as well as a contact phone number. Emergency exam conflicts will be handled on a case-by-case basis. Exam conflicts originating from a lecture conflict will not be accommodated.

Regrade requests are typically open soon after exam scores are released. Late regrade requests will not be considered. If a regrade request is submitted for a part of a question on the exam, the grader reserves the right to regrade the entire exam and could potentially take points off.

You will be allowed to have one page 8.5in X 11in sheet for MT1, two pages for MT2, and three pages for the Final.

Academic Honesty

We treat all our students with utmost trust and respect, and expect students to return the same trust and respect. In EECS16A we will have zero-tolerance for academic dishonesty. There will be dire consequences for students that violate that trust and the Berkeley code of conduct. We are committed to enforcing academic honesty, and dishonesty cases will be punished in their fullest -- no excuses or special circumstances will be considered. Always seek help, never cheat.


Any requests for exceptions should be submitted through this form. Email the exception request as soon as possible, as retroactive exceptions will likely not be approved. Exceptions will be handled on a case-by-case basis. Examples of situations that merit an exception are medical emergencies and family emergencies. No exceptions will be granted after final exam scores have been released.

Accommodations will be provided to students who have letters of accommodations from DSP services and students facing hardships. Accommodations should also be submitted with the above form.

Course Communication

The instructors and TAs will post announcements, clarifications, corrections, etc. on Ed. So, you must check the EECS16A Ed page frequently throughout the term. (You should already have access to the EECS16A Fall 2023 Ed. If you do not, please let us know.)

If you have a question, your best option is to post a message on Ed. The staff (instructors and TAs) will check Ed regularly, and if you use Ed, other students will be able to help you too. When using Ed, please avoid off-topic discussions, and please do not post answers to homework questions before the homework is due. Also, always look for an appropriate category to post the question to (for example, each homework will have its own category, so please post there). That will ensure you get the answer faster.

If your question is personal or not of interest to other students, we encourage you to email us (see the top of this page for all the course emails) rather than making private Ed posts. If you wish to talk with one of us individually, you are welcome to come to our office hours. Please reserve email for the questions you can’t get answered in office hours, in discussion sections, or through Ed.

For any exceptions that are of a personal nature, please contact the head GSI at Technical and homework questions are best resolved in homework party, Ed, and during office hours.

It can be challenging for the instructors to gauge how smoothly the class is going. We always welcome any feedback on what we could be doing better. If you would like to send anonymous comments or criticisms, please fill out this anonymous feedback form.


We encourage you to work on homework problems in study groups; however, you must always write up the solutions on your own. Similarly, you may use books or online resources to help solve homework problems, but you must always credit all such sources in your write up, and you must never copy material verbatim. Using previous EECS 16A homework, exam, and lab solutions is strictly prohibited, and will be considered academic dishonesty. This is not how you want to start your career as an engineer.

We expect that most students can distinguish between helping other students and cheating. Explaining the meaning of a question, discussing a way of approaching a solution, or collaboratively exploring how to solve a problem within your group is an interaction that we strongly encourage. But you should write your homework solution strictly by yourself, and you are not allowed to give your homework to other students to copy. You should never possess a copy (written or digital) of another student’s work. You should acknowledge everyone whom you have worked with, or who has given you any significant ideas about the homework. This is good scholarly conduct.

Collaboration during exams or other designated assessments is strictly forbidden, subject to the Berkeley Honor Code, Code of Conduct, and the parameters of the specific assessment.

16A Study Group Formation

We believe that an important part of learning is learning with others; your study groups will become a crucial factor to your success in all your classes, including EECS16A. To help you find a study group, we have a course-run study group formation program and associated class, EE194: Community in Computing. EE194 is a 1 unit P/NP class in which students will meet weekly with their assigned study groups. While participation is completely optional, we highly encourage you to work in groups. Your very first homework will have an opportunity for you to be matched into study groups based on your preferences!

Don't Be Afraid to Ask for Help

Are you struggling? Please come talk with us! The earlier we learn about your struggles, the more likely it is that we can help you. Waiting until right before an exam or the last few weeks of the semester to let us know about your problems is not an effective strategy - the later it is, the less we will be able to help you.

Even if you are convinced that you are the only person in the class who is struggling, please overcome any feelings of embarrassment or guilt, and come ask for help as soon as you need it -- we can almost guarantee you're not the only person who feels this way. Don't hesitate to ask us for help -- we really do care that you thrive! You can email, or email / talk to any course staff at any time -- we’re happy to help.


If you have COVID symptoms, please do not attend in-person activities. Instead, keep up with the class by watching the lecture recordings. We will post PDFs of each discussion worksheet on the course website, and post detailed solutions the next day, so you can follow along with discussion asynchronously. If you miss a lab section, you should try to make up the lab during buffer week. However, if you would miss multiple labs or miss the buffer section due to illness, please email, and we will do our best to accommodate you. If you have contagious symptoms or COVID please do not attend the exam in person and reach out to us well ahead of the exam time (we will handle these situations on a case-by-case basis).

If you have a medical emergency that would prevent you from keeping up with the class asynchronously or would prevent you from attending class in-person for a longer duration, please email


We are committed to creating an environment welcoming of all students where everyone can fulfill their potential for learning. To do so, we intend to support a diversity of perspectives and experiences and respect each others’ identities and backgrounds (including race/ethnicity, nationality, gender identity, socioeconomic class, sexual orientation, language, religion, ability, etc.). To help accomplish this:

  • If you feel like your performance in the class is being impacted by a lack of inclusion, please contact the instructors, an academic advisor, or the departmental Faculty Equity Advisor (
  • An anonymous feedback form is also available at
  • If you feel like your performance in the class is being impacted by your experiences outside of class (e.g., family matters, current events), please don’t hesitate to come and talk with the instructor(s) or academic advisors in Engineering Student Services. We want to be a resource for you.
  • There is no tolerance for sexual harassment or violence. If your behavior harms another person in this class, you may be removed from the class or the University either temporarily or permanently.
  • If you have a name and/or pronouns that differ from your legal name, designate a preferred name for use in the classroom at:
  • As a participant in this class, recognize that you can be proactive about making other students feel included and respected.

Berkeley Honor Code

Everyone in this class is expected to adhere to this code: “As a member of the UC Berkeley community, I act with honesty, integrity, and respect for others.”

Accommodation policy

We honor and respect the different learning needs of our students, and are committed to ensuring you have the resources you need to succeed in our class. If you need religious or disability-related accommodations, if you have emergency medical information you wish to share with us, please share this information with us as needed. You may write to the course email address and please also see DSP and CAPS under “Resources”.

Policy on Course Content

You are free and encouraged to use course materials for personal use (in collaborations with other students, in your research, etc.). You may NOT post HW/Exams/Solutions anywhere on the web because this could encourage cheating down the road. You are expressly prohibited from uploading course materials to websites such as or, which distribute and monetize content without compensation to the University. Course material, including all video, is copyrighted and reposting to third party sites or any other form of redistribution is prohibited.


For academic performance:

For solving a dispute:

The Ombudsperson for Students (250 Sproul Hall; 510-642-5754) provides a confidential service for students involved in a University-related problem (academic or administrative), acting as a neutral complaint resolver and not as an advocate for any of the parties involved in a dispute. The Ombudsman can provide information on policies and procedures affecting students, facilitate students' contact with services able to assist in resolving the problem, and assist students in complaints concerning improper application of University policies or procedures. All matters referred to this office are held in strict confidence. The only exceptions, at the sole discretion of the Ombudsman, are cases where there appears to be imminent threat of serious harm.

For basic needs (food, shelter, etc):

The Basic Needs Center provides housing, food, transportation support, among other support needed to thrive at UC Berkeley. Specifically, the UC Berkeley Food Pantry (check-in at 1st floor of MLK Student Union) aims to reduce food insecurity among students, especially the lack of nutritious food. Students can visit the pantry as many times as they need and take as much as they need while being mindful that it is a shared resource. The pantry operates on a self-assessed need basis; there are no eligibility requirements. The pantry is not for students and staff who need supplemental snacking food, but rather, core food support.


The following tips are offered based on our experience.

Do the homeworks! The homework is explicitly designed to help you to learn the material as you go along. There is usually a strong correlation between homework scores and final grades in the class.

Keep up with lectures! Discussion sections, labs and homeworks all touch on portions of what we discuss in lecture. Students do much better if they stay on track with the course. That will also help you keep the pace with your homework and study group.

Take part in discussion sections! Discussion sections are not auxiliary lectures. They are an opportunity for interactive learning. The success of a discussion section depends largely on the willingness of students to participate actively in it. As with office hours, the better prepared you are for the discussion, the more you are likely to benefit from it.

Please come to office hours! We love to talk to you and do a deep dive to help you understand the material better.

Form study groups! As stated above, you are encouraged to form small groups (two to four people) to work together on homeworks and on understanding the class material on a regular basis. In addition to being fun, this can save you a lot of time by generating ideas quickly and preventing you from getting hung up on some point or other. Of course, it is your responsibility to ensure that you contribute actively to the group; passive listening will likely not help you much. And recall the caveat above that you must write up your solutions on your own. We strongly advise you to spend some time on your own thinking about each problem before you meet with your study partners; this way, you will be in a position to compare ideas with your partners, and it will get you in practice for the exams. Make sure you work through all problems yourself, and that your final write-up is your own. Some groups try to split up the problems ("you do Problem 1, I'll do Problem 2, then we'll swap notes"); not only is this a punishable violation of our collaboration policies, it also ensures you will learn a lot less from this course.
