Important Information

We will not review the material from ECE459. In particular, you should be very familiar with the material in chapters 2 (Fourier analysis of signals and systems) and 4 (Probability and random processes) of the book.

Usually, I will not give hard copy handouts (such as homework assignments, solutions, information on exams, etc.) in the class. I will email this information to your uiuc.edu accounts. It is important to ensure that there is enough space in your mailbox to receive email. If not, emails will bounce and you may not receive important information.

When computing your final grade, I will drop your lowest homework score. For instance, if you are unable to turn in one of the homework assignments, then you will get a zero for that homework but this will not affect your final grade. Since we have this policy in place, I will not accept any homework that is turned in after the due date.

The homework will be graded by the TA and I will grade all the exams. If you have any questions on your homework score, please check with the TA first and if you are still not satisfied, you are welcome to talk to me.

Grading will be on a curve. Roughly speaking, I will calculate the mean and standard deviation and decide the grade cutoffs (including +/-) based on this. There is no precise formula, but I will give you an idea of what your grade is after each of the two midterm exams.

I will use a single curve for graduate and undergraduate students, but to ensure that it is fair to undergraduate students, the grade cutoffs will be based primarily on the statistics of the undergraduate students’ score.

The webpage http://courses.ece.uiuc.edu/ece461/prev.html contains ECE461 web pages from previous semesters. This is a useful resource for old exams, homework, etc. However, some of the links may not work while others may work with a little bit of modification. You may have to change ece361 (which was the old number for the course) to ece461 in web addresses for some of them to work. If it doesn’t work after this change, then the old web page probably does not exist anymore.
