ECE 438: Digital Signal Processing with Applications

Professor Boutin, Fall 2011

Message area:

A new practice question has been posted below: What kind of signals are band limited?

Please help! We need a table of Discrete Fourier transform pairs and properties!

An idea to get the bonus 3%: make a video explaining how to post equations on Rhea using latex code. (Easiest is to post it on youtube and link to the youtube video from a Rhea page.)

If you want to be notified when a new homework is posted, become your instructor's friends on facebook.

An idea to get the bonus 3%: run collective problem solving pages for ECE301 or some other ECE course. If you can get some students from these courses to actively participate, you could get the full 3%!

Your turn! A bonus point opportunity

Students in ECE438 Fall 2011 have the opportunity to earn up to a 3% bonus by contributing a Rhea page on a subject related to digital signal processing. To pick a subject, simply write your name next to it. Your page will be graded based on content as well as interactions with other people (page views, comments/questions on the page, etc.). The number of links to other courses and subjects will also be taken into account: the more the merrier! Please do not simply copy the lecture notes and do not plagiarize. Read Rhea's copyright policy before proceeding.
