## Your turn! A bonus point opportunity

Students in ECE438 Fall 2013 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.

If you are interested in making a slecture based on Prof. Boutin's material on a specific topic, please contact your instructor.
