I took this course in Fall 2008 at CSUF to learn more about DSP.
This course was hard. The textbook was not too easy, The instructor Dr Shiva has tremendous experience in this subject, and he would explain some difficult things with examples on the board which helped quite a bit. The final exam was hard, it was 7 questions and I had no time to finish them all. It is a very useful course to take to learn about signal processing.
Instructor is professor Shiva, Mostaf, Dept Chair, EE, CSUF.
