MODULATION

is a prescribed method of encoding digital (or analog) signals on a different waveform (the carrier signal). Once encoded, the original signal may be recovered by an inverse process, demodulation. Modulation is performed to adapt the signal to a different frequency range (and medium) than that of the original signal.
