A signal processor is an electronic circuit that removes information from an analog signal as quantifiable units for further analysis. Most modern signal processors are either dedicated microprocessor integrated circuits or general-purpose programmable microprocessors. A digital signal processor (DSP) is an electronic device which serves the purpose of signal processing. It can be used for digital to analog conversions and vice versa.

Famous quotes containing the word signal:
“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)
