ECE 4624 - Digital Signal Processing & Filter Design (3C)

Course Description

Analysis, design, and realization of digital filters. Discrete Fourier Transform algorithms, digital filter design procedures, coefficient quantization. Pre: C or better in 3704

Why take this course?

Digital filters and other signal processing algorithms have become a way of life, since many communication tasks have gone digital. This is clearly expressed by the commercial and consumer availability of products such as FFT-analyzers, coders, and digital video- and audio-disks and players. Many of our graduates will be (in-) directly working in these areas. It is imperative then that they can elect to be provided with an opportunity to familiarize themselves with the basic tools and methods.

Learning Objectives

  • evaluate the performance of a digital filter, in terms of its frequency response;
  • use Fast Fourier Transform techniques for the analysis of arbitrary signals;
  • demonstrate coefficient quantization effects in digital filters;
  • design digital filters using transformation techniques from analog designs;
  • design digital filters using windowing techniques;
  • design digital filters meeting given specifications;
  • organize and write technical reports;
  • organize and make technical presentations.
