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.
