Frequency modulation - Wikipedia, the free encyclopedia (928 words)
Frequency modulation (FM) is a form of modulation which represents information as variations in the instantaneous frequency of a carrier wave.
Problematically, however, frequency drift or lack of selectivity may cause one station or signal to be suddenly overtaken by another on an adjacent channel.
Note that frequency modulation can be regarded as a special case of phase modulation where the carrier phase modulation is the time integral of the FM modulating signal.
