Signal processing is an area of systems engineering, electrical engineering and applied mathematics that deals with operations on or analysis of signals, or measurements of time-varying or spatially varying physical quantities. Signals of interest can include sound, images, and sensor data, for example biological data such as electrocardiograms, control system signals, telecommunication transmission signals, and many others.

Famous quotes containing the word signal:
“Perhaps having built a barricade when youre sixteen provides you with a sort of safety rail. If youve once taken part in building one, even inadvertently, doesnt its usually latent image reappear like a warning signal whenever youre tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (19101986)
