Prerequisite

ECE 421 Introduction to Signal Processing, B average in ECE and MA or Consent of Instructor

Course Objectives

The goals of this course are to provide graduate students with an understanding of discrete–time signals and the analytical tools to analyze and design digital signal processing systems. Upon completion of the course, the students will be able to:

1. design FIR and IIR digital filters to meet arbitrary specifications
2. develop algorithms to implement digital filters using Matlab or other high level languages such as C++,
3. analyze the effects of the use of finite word sizes for the implementation of digital signal processing algorithms,
4. develop and analyze algorithms for multirate digital signal processing, and
5. be able to design and implement digital signal processing algorithms for applications related to digital communications, data acquisition,spectrum analysis, etc.
