Frequency modulation

frequency modulation

World Encyclopedia | 2005 | Copyright

frequency modulation (FM) Form of radio transmission. It is the variation of the frequency of a transmitted radio carrier wave by the signal being broadcast. The technique makes radio reception fairly free from static interference and, although restricted in range to receivers in line-of-sight of the transmitter, has become the most favoured transmission method. See also amplitude modulation (AM)
