Introduction to digital signal processing of continuous and discrete signals. The family of Fourier transforms including the discrete Fourier transform (DFT). Development of the fast Fourier transform (FFT). Signal sampling and reconstruction. Design and analysis of digital filters. Correlation and spectral estimation. It addresses the following topics: sampling and quantization, multirate digital systems, discrete Fourier transform (DFT), windowed DFT, fast Fourier transform (FFT), digital filter design, decimation and interpolation filters, linear predictive coding, and an introduction to adaptive filtering.
