ECE 210/211 - Fall 2022

About the course

ECE 210 is the first mathematically oriented course in the electrical and computer engineering curricula. The course begins by building on the circuit analysis concepts you learned in ECE 110 and then progresses into the more abstract world of Fourier and Laplace transforms. Much of what we will do will rely on your background in calculus. Our goal will be to apply mathematical tools to the analysis and design of signal processing systems, culminating in a thorough understanding of an AM radio receiver and the ability to design simple filters. ECE 210 deals with the processing of continuous-time, or analog signals. The follow-on course, ECE 310, covers the processing of sampled, or digital signals. Full description, including course goals and instructional objectives, can be found here.

ECE 211 is the first half of ECE 210. Students in ECE 211 should attend lectures approximately through Friday, October 14 (Chapters 1 through 6 in the course textbook). Full description, including course goals and instructional objectives, can be found here.

DISCUSSION

Active participation in your learning environment is vital to your success in this course.

Campuswire: For discussions and questions regarding course material. Code to join: 6947

Student online behavior: In any social interaction, certain rules of etiquette are expected and contribute to more enjoyable and productive communication. The following are tips for interacting online via e-mail or discussion board messages, adapted from guidelines originally compiled by Chuq Von Rospach and Gene Spafford (1995):

Remember that the person receiving your message is someone like you, deserving and appreciating courtesy and respect.
Be brief; succinct, thoughtful messages have the greatest effect.
Your messages reflect on you personally; take time to make sure that you are proud of their form and content.
Use descriptive subject headings in your e-mails.
Think about your audience and the relevance of your messages.
Be careful when you use humor and sarcasm; absent the voice inflections and body language that aid face-to-face communication, Internet messages are easy to misinterpret.
When making follow-up comments, summarize the parts of the message to which you are responding.
Avoid repeating what has already been said; needless repetition is ineffective communication.

GRADING POLICIES

It is the student's responsibility to check that the correct grades are entered in CANVAS.

The final grade will be calculated as follows:

Grading for ECE 210:
3 Midterm exams.................. 45%
Final Exam............................ 25%
Quizzes................................. 10%
Weekly homework................ 10%
Labs...................................... 10%

Grading for ECE 211:
Final Exam (Exam 2)............. 35%
1 Midterm exam..................... 30%
Quizzes................................... 20%
Weekly homework................. 15%

In order to account for sickness, travel or internet issues, your two lowest homework grades will be dropped (only one for ECE 211).

As a rough guideline, we intend to award letter grades as indicated below, where 'm' is the mean and 's' is the standard deviation.

some type of A if
- m+s < grade
some type of B or better if
- m < grade < m+s
some type of C or better if
- m-s < grade < m
some type of D or better if
- max(45,m-2s) < grade < m-s
F
- grade < max(45,m-2s)

HOMEWORK ASSIGNMENTS

Homework assignment policy:

Homework assignments constitue 10% of the course grade.
Homeworks will be posted every Tuesday in Gradescope and Canvas and will be due the following Tuesday by 11.59pm. The first homework will be due on Tuesday, August 30 by 11.59pm.
Submissions will be made via Gradescope. You can join the course there with the entry code 8NEND8, use your UIN as your Student ID #.
- Instructions for uploading your solutions to Gradescope can be found here.
- Gradescope now has a mobile app to make it easier to upload.
- Instructions on how to scan the pdf of the solutions in Android are here.
- Instructions on how to scan the pdf of the solutions in MacOS are here.
Late homeworks will be deducted 12.5% per late hour, so after 8 hours, you will get zero, so please mark your calendar with the deadlines to avoid losing points.
Do not wait until the last minute to submit it and then run into internet issues.
In order to account for sickness, travel or internet issues, your two lowest homework grades will be dropped (only one for ECE 211).
Do not solve the HW directly on the provided pdf because there is not enough space for it.
Make sure you box your final answers and match problem parts accurately in Gradescope, or you will be deducted 5% of the corresponding problem part.
Make sure that your homeworks are neat enough to read. Graders has the flexibility to deduct points for lack of neatness.
You will be expected to provide detailed explanations of your solutions in order to obtain credit in your homeworks. Graders should not have to guess or make assumptions about why you are using a certain equation, or how you came up with an equation, etc. Conversely, solutions lacking full explanations will receive zero credit even when the answer provided may be correct.
Please report angles in radians and in the range (-pi,pi]. Failure to do so could result in loss of some credit.
Homeworks constitute an essential component of your learning experience in the course and prepare you for your exams in effective ways. Investing time to do your homeworks with care will pay off when you are taking your exams.
Solutions will be posted in Canvas 8 hours after the corresponding deadline.
Regrades: You will receive an email from Gradescope so you can log in and see your graded homework. If after looking at the posted solutions, you feel there was an inaccuracy in the grading of your homework, you can request a regrade within Gradescope itself.
Make sure you submit regrade requests before 11.59pm of the Tuesday after your graded homework is made available via Gradescope. Regrades will not be accepted after that date.

Conflict exam requests:

Our exam schedule was posted since the first day of the semester: September 21, October 19 and November 16, all from 7-8.15pm.
Some of you either have classes, labs, or other exams that overlap with our exams. We will offer conflict exams for those of you who are in these situations but you need to get Prof. Alvarez's approval in order to be able to take the conflict exams.
As indicated in the student code, conflict exams are to be granted if the student informs the instructor of the conflict within one week after being informed of the examination schedule. Priority will be given to the examination announced in class the earliest in the semester.
If you have conflicts with one or more of our exams and want to request a conflict exam, you must complete this form by Tuesday, September 6.
If you do not have access to the form, please email Prof. Alvarez.

Absences from exams:If you miss an exam due to illness, injury, family emergency or other reasons beyond your control, you will be asked to provide your professor with an absence letter from the Student Assistance Center in the Office of the Dean of Students. Documentation which validates the absence is required by the Dean's Office to provide the absence letter. The absence letter will serve to verify the reason for your absence from the exam. Prof. Alvarez will then take an appropriate action that may include offering an oral examination or written examination.

Regrades:

We will use Gradescope to grade the exams, so you will receive an email from Gradescope to log in and see your graded exam. If after looking at the posted solutions, you feel there was an inaccuracy in the grading of your exam, you can request a regrade within Gradescope itself.
Do not submit a regrade asking for more partial credit because you did so much work nor because you think something should be worth more/less that it does. Only regrades regarding inaccurate grading will be addressed.
Regrades could be subjected a regrading of the entire exam, no just those parts you indicate. Therefore, your grade could go up or down as appropriate.
You will get an email from the instructors after the exams are graded indicating when you can start submitting regrades and when the deadline to submit the regrades is.
Make sure you submit regrade requests by the deadline indicated in that email, so do not wait until the last minute to submit it and then run into internet issues. No regrade requests will be accepted after the deadline.

Old exams for practice can be found here.

Open office hours

Office hours on Monday and Tuesday are open hours where all types of questions are allowed, and we have found that students mostly use them to ask about the upcoming homework.
Course staff will not give you the answers nor check if your answer is correct. Course staff will help you see if your approach is correct/incorrect, and guide you accordingly.
Lab questions might be referred to the open lab times.

Small study session office hours

We also have additional office hours each week of support for you by having small study sessions with course staff members to answer conceptual questions, provide additional examples, etc. but nothing related to that week's HW.
These sessions will be available on Thursdays and Fridays by signing up via this online form before 8am each Thursday.
The signup is voluntary but we do expect your attendance and participation regularly if you do sign up for a slot. Due to limited space, please avoid missing your slot. More than one missed attendance will prevent you from signing up for the remainder of the semester.
You can add/remove yourself from the timeslot at any time before 8am on Thursday of the corresponding week.
Once you sign up for a slot, it will be assumed that you will attend that slot from then on, so please remember to unregister if you will no longer attend.
If you do not have specific questions, but you want to get some practice and help at the same time, you can can ask the staff member to provide some example to practice.

HKN late-night office hours

HKN will be hosting late-night office hours for the rest of this semester Sunday-Thursday night from 8pm-12am.
Here is the link to the schedule. It will be updated every week.

COURSE STAFF

Instructors:

TA's:

Communication: It is the student's responsibility to attend lectures and check their email daily, in case there are announcements from course staff. Missing a lecture and/or not checking your email will not excuse complying with course deadlines and policies.

Please post your questions on the discussion board, Campuswire, instead of emailing the instructors or TAs directly because it is very likely that you're not the only one of enrolled in the course that has that same question. This way, others can take advantage of the responses to your questions, and other students might be able to assist you sooner.

HONORS

ECE 210 Honors will introduce students to Python programming through modules in Jupyter notebook. As such, prior Python experience would be helpful, but definitely not required. We’ll teach everything from the ground up.

You do not have to be a James Scholar to sign up but you will only get the 'H' in your transcript if you are.

If you are a James Scholar, you must complete the corresponding HCLA form from the College and submit it before September 12.

The sessions will start the week of September 26.

There is more information and a signup form here. Please complete by September 12 if you want to participate.

Academic integrity

The University of Illinois at Urbana-Champaign Student Code should is very important for you to know.

Students should pay particular attention to Article 1, Part 4: Academic Integrity. Academic dishonesty may result in a failing grade. Every student is expected to review and abide by the Academic Integrity Policy. Ignorance is not an excuse for any academic dishonesty. It is your responsibility to read this policy to avoid any misunderstanding. Do not hesitate to ask the instructor(s) if you are ever in doubt about what constitutes plagiarism, cheating, or any other breach of academic integrity.

Inclusivity

The effectiveness of this course is dependent upon the creation of an encouraging and safe classroom environment. Exclusionary, offensive or harmful speech (such as racism, sexism, homophobia, transphobia, etc.) will not be tolerated and in some cases subject to University harassment procedures. We are all responsible for creating a positive and safe environment that allows all students equal respect and comfort. I expect each of you to help establish and maintain and environment where you and your peers can contribute without fear of ridicule or intolerant or offensive language.

Disability Resources and Educational Services (DRES)

Students with documented disabilities must notify the instructor within the first 7 days of classes.

To obtain disability-related academic adjustments and/or auxiliary aids, students with disabilities must contact the course instructor and the Disability Resources and Educational Services (DRES) as soon as possible.

To contact DRES, you may visit 1207 S. Oak St., Champaign, call 333-4603, e-mail disability@illinois.edu or go to the DRES website.

If you are concerned you have a disability-related condition that is impacting your academic progress, there are academic screening appointments available on campus that can help diagnosis a previously undiagnosed disability by visiting the DRES website and selecting â€œSign-Up for an Academic Screeningâ€� at the bottom of the page.

FERPA

Any student who has suppressed their directory information pursuant to Family Educational Rights and Privacy Act (FERPA) should self-identify to the instructor to ensure protection of the privacy of their attendance in this course. Click here for more information on FERPA.

Sexual misconduct

The University of Illinois is committed to combating sexual misconduct. Faculty and staff members are required to report any instances of sexual misconduct to the Universityâ€™s Title IX and Disability Office. In turn, an individual with the Title IX and Disability Office will provide information about rights and options, including accommodations, support services, the campus disciplinary process, and law enforcement options. A list of the designated University employees who, as counselors, confidential advisors, and medical professionals, do not have this reporting responsibility and can maintain confidentiality, can be found here. Other information about resources and reporting is available here.

Support Resources and Supporting Fellow Students in Distress

As members of the Illinois community, we each have a responsibility to express care and concern for one another. If you come across a classmate whose behavior concerns you, whether in regards to their well-being or yours, we encourage you to refer this behavior to the Student Assistance Center (1-217-333-0050) or online. Based upon your report, staff in the Student Assistance Center reaches out to students to make sure they have the support they need to be healthy and safe. Further, as a Community of Care, we want to support you in your overall wellness. We know that students sometimes face challenges that can impact academic performance (examples include mental health concerns, food insecurity, homelessness, personal emergencies). Should you find that you are managing such a challenge and that it is interfering with your coursework, you are encouraged to contact the Student Assistance Center (SAC)in the Office of the Dean of Students for support and referrals to campus and/or community resources. The SAC has a Dean on Duty available to see students who walk in, call, or email the office during business hours. For mental health emergencies, you can call 911 or contact the Counseling Center.

Run, hide, fight.

Emergencies can happen anywhere and at any time. It is important that we take a minute to prepare for a situation in which our safety or even our lives could depend on our ability to react quickly. When weâ€™re faced with almost any kind of emergency â€“ like severe weather or if someone is trying to hurt you â€“ we have three options: Run, hide or fight.

Run, hide, fight video.

	Run Leaving the area quickly is the best option if it is safe to do so. Take time now to learn the different ways to leave your building. Leave personal items behind. Assist those who need help, but consider whether doing so puts yourself at risk. Alert authorities of the emergency when it is safe to do so.
	Hide When you canâ€™t or donâ€™t want to run, take shelter indoors. Take time now to learn different ways to seek shelter in your building. If severe weather is imminent, go to the nearest indoor storm refuge area. If someone is trying to hurt you and you canâ€™t evacuate, get to a place where you canâ€™t be seen, lock or barricade your area if possible, silence your phone, donâ€™t make any noise and donâ€™t come out until you receive an Illini-Alert indicating it is safe to do so.
	Fight As a last resort, you may need to fight to increase your chances of survival. Think about what kind of common items are in your area which you can use to defend yourself. Team up with others to fight if the situation allows. Mentally prepare yourself â€“ you may be in a fight for your life

Please be aware of people with disabilities who may need additional assistance in emergency situations
