Digital Signal Processing
MIT OpenCourseWare presents this 1987 distance-education course built by the MIT Center for Advanced Engineering Studies for working engineers and scientists. It covers the analysis and representation of discrete-time signals and systems, including discrete-time convolution, difference equations, the z-transform, and the discrete-time Fourier transform, with attention to how these compare to continuous-time systems. Later sections move into digital network structures and nonrecursive (FIR) digital filters, closing with digital filter design and the fast Fourier transform algorithm for computing the discrete Fourier transform. Materials include video lectures and course documents from the original distance-learning production. No certificate is offered, consistent with MIT OpenCourseWare's format, but all lecture content and problem materials are free to access.
