frequency modulation in English

noun
1
the modulation of a radio or other wave by variation of its frequency, especially to carry an audio signal.
These data were not used to measure time lags between the acoustic and seismic channels, but merely to demonstrate the similarity in frequency modulation and duration of signals in both the air and ground.
