Digital Signal Processing (DSP) refers to the use of mathematical algorithms to manipulate digital signals in order to extract information or enhance the quality of the signal. Some synonyms for DSP include digital filtering, signal analysis, signal processing algorithms, and waveform processing. Other related terms include audio processing, image processing, and video processing, which all involve the manipulation of digital signals for specific purposes. DSP is a key technology in modern electronics, telecommunications, and computer science, and is used in a wide range of applications from audio and video compression to medical imaging and speech recognition. Mastering DSP requires a strong foundation in mathematics, programming, and signal theory.
