[dē′mäj·ə‚lāt]
(communications)
To recover the modulating wave from a modulated carrier. Also known as decode; detect.

demodulate

demodulate

To isolate a data signal from a carrier wave. The demodulation circuit uses the unmodulated carrier as a reference signal and compares it to the received signal. See modulation and carrier.
