ECE 4624 Digital Signal Processing & Filter Design (3C)
Analysis, design, and realization of digital filters. Discrete Fourier Transform algorithms, digital filter design procedures, coefficient quantization. Pre: C or better in 3704
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.
Capstone Technical Elective for EE; Technical Elective for CPE. Typically offered: Fall, Spring. Program Area: Communications.
Prerequisites: C- or better in 3704.
The basic treatment of deterministic continuous and digital filter concepts (as in 3704) form the foundation upon which one builds the analysis and design of digital filters and signal processing algorithms.
