Text – Discrete-Time Signal Processing, 2nd Ed., Oppenheim and Schafer, Prentice Hall: 1998.
also, we will be referring to the draft text for this course Fixed Point Signal Processing, Wayne Padgett and David
Anderson this will be available on Angel and will change during the quarter as I add to it.
Reading – You are expected to have read the textbook assignments given above before you come to class. This course
will require you to actively participate by solving problems and asking questions in class.
Instructor – Wayne Padgett, Room: Wayne.Padgett@Rose-Hulman.edu (emailing your questions is encouraged, I will
often be able to respond in the evenings, use the Angel Homework forum when possible)
Homework – Homework will be assigned regularly and is due in the format specified in the ECE Departmental Writing
Guidelines at the beginning of the period.
Grades – The grading policy for this course is stated in ECE483 General Information.
