From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:



  demodulation
       
           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.
