ECE 210/211 - Spring 2023 (2024)

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, March 10 (Chapters 1 through 6 in the course textbook). Full description, including course goals and instructional objectives, can be found here.

ATTENDANCE

• iClickers:
  • In order to encourage attendance, iClickers will be used to take attendance.
  • You must register your iClicker device using your @illinois.edu email. The system will not be able to assign your attendance to you until you register your remote. Once you register it, any attendance points from your remote will be assigned to you.
  • Students that attend at least 76% of lectures prior to the end of a quiz period, and use their iClickers to record the attendance by answering polls during lectures, will be allowed to retake the quiz. The 76% minimum is to allow for sickness and other unforeseen situations.
    • More information on how this works can be found in the quizzes section of the website.
  • Clicking attendance for another student, or using the app to click without being physically in the lecture room, will both result in an academic integrity violation with sanctions ranging from a letter grade reduction to an F in the course.
• Lecture attendance is not required but is is strongly recommended in order for you to learn the course material well and obtain a good grade in the course.
• If you miss a lecture, you can watch AL1 section's recording in the course's Mediaspace channel

Communication: It is the student's responsibility to attend lectures and the course announcements in Canvas, 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.

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: 2760.

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:

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 will be due the following Tuesday by 8pm. The first homework will be due on Tuesday, January 24 by 8pm.
  
• Submissions will be made via Gradescope.
  • 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 accepted up to 12 hours after the deadline with a deduction of half of the points (no negative final score), 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 because we will not give you an extension. Submit your HW as soon as you finish it because if you wait and forget to do it on time, we will not give you an extension.
  
• In order to account for sickness, travel or internet issues, your two lowest homework grades will be dropped (only one for ECE 211).
  
• 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 your submission is complete before logging out of Gradescope because we will not give an extension if you do not complete the submission. You will receive an automated email from Gradescope that includes the date and time you turned in the assignment, so make sure you get it.
  
• Make sure that your homeworks are neat enough to read. Graders has the flexibility to deduct points for lack of neatness. Graders should not have to guess what you wrote and where in the page you wrote it. An easy to follow solution is required.
  
• Do not solve the HW directly on the provided pdf because there is not enough space for it and you will most likely lose points due to lack of neatness.
  
• 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.
  
• 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, or what polarity you used, etc. Conversely, solutions lacking full explanations will receive zero credit even when the answer provided may be correct, and may lead to an 'academic integrity violation' case being opened against you with sanctions ranging from a letter grade reduction to an F in the course.
  
• You are encouraged to collaborate to understand the problems in the assignment, but each student should solve the problems individually for submission even if they work together initially to understand how to solve the problems. Copying a joint solution or someone else's solution is not acceptable and may lead to an 'academic integrity violation' case being opened against you with sanctions ranging from a letter grade reduction to an F in the course.
  .
• Using previous semester homework solutions and online solutions (Chegg, etc.) may lead to an 'academic integrity violation' case being opened against you with sanctions ranging from a letter grade reduction to an F in the course.
  .
• Please keep these cautionary remarks in mind as you are working out your assignments and avoid submitting unsubstantiated solutions to avoid any misinterpretations.
  
• Solutions will be posted in Canvas 12 hours after the corresponding deadline.
  
• Please report angles in radians and in the range (-pi,pi]. Failure to do so could result in loss of some credit.
  
• 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 8pm of the Tuesday after your graded homework is made available via Gradescope. Regrades will not be accepted after that date.

• 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 Sunday, January 29.
• If you do not complete the form by the deadline, we are not required to grant a conflict exam.
• If you do not have access to the form, please email Prof. Alvarez.

Absences from exams: You MUST notify Prof. Alvarez before missing an exam. 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,. 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.

QUIZZES

• Quizzes constitute 10% of your ECE 210 grade or 20% of your ECE 211 grade.
• Quizzes will be administered using PrairieLearn at CBTF over a 4 day period on the dates below.
• You must register for the quizzes through the PrairieTest website.
• You can register as early as two weeks before the quiz and we strongly recommend you sign up for the first day, in case you get sick. If you sign up for the last couple of days and you get sick, you might not be granted an extension.
• ECE 210 students will take three quizzes.
• ECE 211 students will take just the first two quizzes.
• Quizzes are closed notes. However, we will provide the following tables from the textbook: 6.1, 6.3, 7.1, 7.2, 9.1, 9.3, 11.1 and 11.2 (or 1-8 from the online table handout) as needed.

• Students that attend at least 76% of lectures prior to the end of a quiz period, and use their iClickers to record the attendance by answering polls during lectures,will be allowed, but not required, to retake the quiz.
  • The retake exam will likely have different problems than those in the original exam.
  • Your score on the retake does not directly replace your quiz score, but modifies it as indicated by the following formula:
    grade = MAX( Q, [ Q + R*(100-Q)/(100-72) ] / [ 1 + (100-Q)/(100-72) ] ),
    where Q is the grade in the original quiz and R is the grade in the retake.
  • Notice that your grade would not go down if you attempt the retake.
  • The potential benefit is higher for students who had weaker performance on the original quiz.

The quiz dates/times are as follows:

If it is due to an excused absence, please also provide the corresponding documentation.

Here are the Univeristy's policies if you test positive for COVID.

Here is the information for quarantine and isolation.

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, hom*ophobia, 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 “Sign-Up for an Academic Screening� 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 University’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.

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 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 can’t or don’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 can’t evacuate, get to a place where you can’t be seen, lock or barricade your area if possible, silence your phone, don’t make any noise and don’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 – you may be in a fight for your life
