ECE301:"Signals and Systems", Spring 2011, Professor Boutin
Message Area:
1. HW 9 is posted. It is due next Wednesday.
2. Does anybody know seniors or grad students in BME who could help explain the relevance of EE301 for a BME student? If so, please encourage them to write their comments about ECE301 on Rhea's peer legacy page.
3. Wanted: More pairs and properties in our collective tables of CT Fourier transforms and DT Fourier transforms! See bonus point opportunity below.

Relevant Resources
Your turn! A bonus point opportunity
All ECE301 students in Prof. Mimi's section have the opportunity to earn up to a 3% bonus on their course grade by contributing a Rhea page on a subject related to signals and systems. Examples of subjects are listed below. Feel free to come up with your own. To pick a subject, write your name next to it in the table below. Then when you begin writing your page, also post a link to it in the appropriate space (where it says "put link to your page here"). 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.
