Digital signal processing DSP is the use of digital processing , such as by computers or more specialized digital signal processors , to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics , a digital signal is represented as a pulse train , [1] [2] which is typically generated by the switching of a transistor. Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include audio and speech processing , sonar , radar and other sensor array processing, spectral density estimation , statistical signal processing , digital image processing , data compression , video coding , audio coding , image compression , signal processing for telecommunications , control systems , biomedical engineering , and seismology , among others.

A signal is a description of how one parameter varies with another parameter. For instance, voltage changing over time in an electronic circuit, or brightness varying with distance in an image. A system is any process that produces an output signal in response to an input signal. This is illustrated by the block diagram in Fig.
