EE345S Real-Time Digital Signal Processing Laboratory - Midterm #1

Midterm #1 for the Spring 2006 semester will be on Thursday, March 9th, during lecture time (5:00 to 6:30 PM) in ENS 115.

Midterm #1 will be an open book, open notes exam scheduled to last the entire period. Midterm #1 questions will come from lecture and lab. It is possible that one problem on the midterm may require you to write TMS320C6000 C/assembly code.
