demodulate
(foldoc) | demodulation
demodulate
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.
