demodulation:

see modulationmodulation,
in communications, process in which some characteristic of a wave (the carrier wave) is made to vary in accordance with an information-bearing signal wave (the modulating wave); demodulation is the process by which the original signal is recovered from the wave

demodulation

[dē‚mäj·ə′lā·shən]
(communications)
The recovery, from a modulated carrier, of a signal having substantially the same characteristics as the original signal.

demodulation

Electronics the act or process by which an output wave or signal is obtained having the characteristics of the original modulating wave or signal; the reverse of modulation

demodulation

(communications)
To recover the signal from the carrier. For example, in a radio broadcast using amplitude modulation the audio signal is transmitted as the mean amplitude of a radio-frequency carrier so demodulation requires a circuit which measures the amplitude and filters out the carrier. There are many other kinds of modulation and corresponding demodulation.
