Prerequisites: EE 7372, Digital Signal Processing

Text: Discrete-Time Signal Processing, Thomas Quatieri

Prentice-Hall, 2002 (Required)

Digital Processing of Speech Signals, L. Rabiner & R. Schafer

Prentice-Hall, 1978 (Optional)

Grading: Homework 20%

Computer projects 50%

Final Exam 30% (Sat, May 1, 11:30-14:30)

Homework & Computer Projects:

The homework will be more of the analytical type.

Computer projects will require you to process signals and then view and listen to them.

The processing should be done using MATLAB, and the MATLAB files should accompany

the project, to be able to duplicate your results.

Late homework: Solutions will be given on the lecture period after the homework iscollected. No homework will be accepted after solutions are posted.

Late projects: The projects due date for distance education students will be one lecture

period after the in-class students. The grade will be reduced by 10% for every lecture

period you miss in turning it in. No projects will be accepted after the last day of classes.

Feedback: After every lecture:

What stood out as most important in todays lecture?

What are you confused about?
