Nonlinearity is the behavior of a circuit, particularly an amplifier, in which the output signal strength does not vary in direct proportion to the input signal strength. In a nonlinear device, the output-to-input amplitude ratio depends on the strength of the input signal.

Array processing is an important application of digital signal processing which can be found in radar, sonar, communications, seismology, biomedical engineering, and radar astronomy, among others.
