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.

ECE 210 course description
ECE 210 class schedule

ECE 211 is the first half of ECE 210. Students in ECE 211 should attend lectures approximately through Friday, March 8 (Chapters 1 through 6 in the course textbook).

Exams will be combined for all sections of ECE 210 and 211.
ECE 210 students will take three evening tests and a final exam.
ECE 211 students will take just the first two tests. The second test will serve as the final exam for ECE 211 students.
To compensate for the evening tests, class will be canceled on the next day after each test.
  • Exam 1:
    • Thursday, February 14, 8:45-10 p.m.
    • Review: Tuesday, February 12, 7-9 p.m., 3013 ECEB.
    • HKN Review: Sunday, February 10, 1-3 p.m., 1013 ECEB.
    • Exam 1 Solution
    • Regrade deadline: Wednesday, February 27 at 6 p.m. in exam regrade box
  • Exam 2:
    • Thursday, March 14, 8:45-10 p.m.
    • Review: Tuesday, March 12, 7-9 p.m., 3013 ECEB.
    • HKN Review: Sunday, March 10, 1-3 p.m., 1015 ECEB
  • Exam 3:
    • Thursday, April 18, 8:45-10 p.m.
    • Review: Tuesday, April 16, 7-9 p.m., 3013 ECEB.
    • HKN Review: TBD
  • Final Exam:
    • Time: TBD
    • Review: TBD
All exams will be closed book, closed notes. Calculators, laptop computers, cell phones, tables of integrals, etc. are neither necessary nor permitted. Electronic devices of any sort such as calculators, laptops, PDAs, cellphones, pagers, iPods or other MP3 players etc. are not permitted.

Absences from Hour Exams:

If you miss an hour 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. Your ECE 210 professor will then take an appropriate action that may include offering an oral examination or written examination.


If when you receive your graded exam, and after looking at the posted solutions, you feel there was an inaccuracy in the grading of your exam, write down the question and reason that you want to regrade and staple it to your exam BUT do not write on or alter in any way your original exam paper. Turn in such regrade requests, by the deadline given in the email sent out by the course coordinator, in the ECE 210/211 Exam Regrade box (not the HW regrade box) located on the northwest corner of the 3rd floor of ECEB, next to the service elevator. If you pick it up late you do not get an extension.

Written assignments will be made weekly on the link "Homework Assignments and Solutions" and will be due on Wednesdays at 6 p.m. in the homework boxes located on the northwest corner of the 3rd floor of ECEB, next to the service elevator.
The lowest homework mark will be dropped for 211 students and the lowest two homework marks will be dropped for 210 students.
You can check your homework marks on Illinois Compass 2g.


Homework format: The HW solution should be readable, clearly written. In the case it isn't, students will be penalized with reduction of points or zero credits (see policy below). The header should be in a format, left side up corner: course number, section, and semester; right side up corner: student name and netID; and in the middle HW1,2, etc. See the following picture as an example:


Homework Policy:

  1. Written assignments are due every Wednesday at 6 p.m. in the homework boxes located on the northwest corner of the 3rd floor of ECEB, next to the service elevator. Late homework (even by a minute) will receive no credit. Each section has its own box.
  2. When you submit your homework, be sure that your name, section, and NetID are printed neatly at the top of the page. This will ensure that your score is recorded correctly. Note that your NetID is not your UIN. If you fail to write your section, you will lose 10% of the total allocated score for that assignment. Homeworks with missing or illegible name and netID will be deducted 50% of the allocated score.
  3. All homework must be stapled. If you fail to staple your homework, you will lose 10% of the total allocated score. If you fail to staple and your pages become lost only the pages with your name on them will be graded. There is a stapler in undergrad lounge and the advising office.
  4. As the semester goes on, you may find that you attend a different lecture than you are enrolled in. If you want to get back your HW from the section that you are attending, you can submit your homework to the box corresponding to the lecture you actually attend. When using this option, you must make a note saying "Enrolled in ALX, Please return to ALZ". Otherwise, 10% of the total allocated score will be deducted.
  5. Make sure that your HW is neat enough to read. Graders has the flexibility to deduct up to 20% for lack of neatness. Doing things like boxing your answers, showing ALL of your work, and generally making it easier for the graders to grade will overall increase your scores on HW.
  6. Homework assignments in ECE 210 constitute an essential component of your learning experience in the course and prepare you for your mid-term 'hour exams’ and the end-of-semester ‘final exam’ in most effective ways — investing time to do your homework 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 full credit in your homework assignments. Conversely, solutions lacking full explanations will receive zero credit even when the answer provided may be correct and furthermore incorrect answers without any work shown may lead to 'academic integrity violation' cases being opened against you. Some of the homework problems you will be assigned will resemble problems from previous semesters but with modified parameters and/or inputs. Your comprehensive homework solutions will naturally be expected to match the versions of the problems assigned during the current semester, whereas solutions or answers matching the versions from previous semesters will once again lead to 'academic integrity violation' cases being brought against you.
    Please keep these cautionary remarks in mind as you are working out your homework assignments and avoid submitting unsubstantiated solutions to avoid any misinterpretations as explained above.
  7. If you miss lecture on the day that assignments are handed back, they will be kept in the card box next to the wooden cabinet in 3030.
  8. Regarding regrades: if you want to request a regrade for your assignment, you must do so within a week of getting your assignment back. The regraded assignments will be returned with the assignment due the coming Wed after you submitted your regrade. To request a regrade, on a separate piece of paper, write which problem you would like regraded as well as why you think it is correct. Staple this paper to your assignment and then turn it in to the regrade requests box, located on the northwest corner of the 3rd floor of ECEB, next to the service elevator.
