demodulation
    n 1: (electronics) the reception of a signal by extracting it
         from the carrier wave

from The Free On-line Dictionary of Computing (8 July 2008)

demodulation
demodulate

   <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.
