Questions tagged [signal-processing]

AKA digital signal processing (DSP). A signal is an information-carrying wave, but in the digital sense, a 'signal' refers to either received or transmitted streams/blocks of data, commonly representing real-world quantities such as audio levels, luminosity, pressure etc over time or distance. 'Processing' is the act of altering, analyzing or characterizing the data to retrieve/modify information inherent in the signal in question.
