digiatl signal processing Digital Signal Processing (DSP) is the use of mathematical algorithms to process signals, which are typically represented as digital data. DSP techniques are widely used in a variety of applications, such as audio and video processing, communication systems, control systems, and biomedical signal processing. The primary goal of DSP is to analyze, manipulate, and transform signals to extract useful information or enhance their quality. Common DSP operations include filtering, spectral analysis, signal synthesis, and compression.
