ECE 5620 Advanced DSP & Filter Design (3C)
Advanced analysis, design, and realization of digital filters. Efficient Discrete Fourier Transform algorithm implementations, finite wordlength arithmetic, fixed point implementation, limit cycles, noise shaping, decimation and interpolation, multi-rate digital filter design, Hilbert transformers, analytic signal generation, basic adaptive filtering.
Digital filters and other signal processing algorithms have become integral aspects of many applications, for example in wireless communications, medical instrumentation, and various digital video and audio consumer products. Many of our graduates will be directly working in these areas, and need a solid background in the details necessary for efficient and practical implementations.
Typically offered: Spring. Program Area: Communications.
Prerequisites: 4624, STAT 4714.
A solid background in deterministic digital filter concepts (as in 4624) and an introduction to probabilistic concepts used in the context of system analysis (as in STAT 4714) form the foundation upon which one builds the advanced analysis and design of digital filters and signal processing algorithms.
