Subcategories

• Acoustic signal processing - the receiving and interpretation of acoustic signals
• Adaptive signal processing - signal processing that adapts its transfer function according to an algorithm driven by an error signal
• Array signal processing - the processing of signals using multiple, spaced receivers
• Chirp - commonly used in sonar and radar, a signal in which the frequency increases or decreases over time
• Convolution - a mathematical process operating on two functions which produces a third function that is a modified version of one of the original functions
• Decorrelation - any process that is used to reduce autocorrelation or cross-correlation within or between signals while preserving other aspects of the signal
• Digital signal processing - the receiving and processing of digital signals
• Distortion - the alteration of the original shape of a signal
• Effects - the results of a signal
• Geophysical signal processing - receiving and processing signals resulting from Earth functions
• Modulation - the process of varying one or more properties of a high-frequency periodic waveform with a modulating signal, which contains the information to be transmitted
• Optical signal processing - the processing of signals in lights
• Radar signal processing - the receiving and interpretation of radar waves
• Source separation - separating different digital signals coming from different sources
