Digital signal processing Digital signal processing Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time‚ discrete frequency‚ or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. The goal of DSP is usually to measure‚ filter and/or compress continuous real-world analog signals. The first step is usually to
