'''Frequency modulation''' (FM) is a signaling method that varies the carrier [[frequency]] in proportion to the [[amplitude]] of the modulating signal.  

Frequency modulation is most commonly used in [[radio]], [[amateur radio]], [[radar]], telemetry, [[seismic]] prospecting, and in the monitoring of [[baby|newborn]]s for [[seizure]]s via [[EEG]].<ref>B.
