General description

The course focuses on linear filtering of discrete-time signals. Main topics are related to digital filter design/realization techniques, Discrete Fourier Transform/FFT implementation and its use, linear adaptive filtering. Fixed/floating point representation and finite precision effects are presented. Applications include audio signal processing, coding algorithms, multirate signal processing. Hardware implementations issues are also outlined, related to pipelining and algorithm transformation (retiming, folding, unfolding).
