'''Digital signal processing''' ('''DSP''') is made of two things: the study of [[Signal (information theory)|signal]]s in a [[digital]] representationform, and the processing methods of theseprocessing said signals. DSP and [[analog signal processing]] are subfields of [[signal processing]]. DSP has three major subfields: [[audio signal processing]], [[digital image processing]] and [[speech processing]].

Since the goal of DSP is usually to measure or filter continuous real-world analog signals, the first step is usually to convert the signal from an analog to a digital form, by using an [[analog to digital converter]]. Often, the required output signal is another analog output signal, which requires a [[digital to analog converter]].
