Noun
modulation of the frequency of the (radio) carrier wave
Source: WordNetAlthough the bandwidth of an AM signal is narrower than one using frequency modulation (FM), it is twice as wide as single-sideband techniques; it thus may be viewed as spectrally inefficient. Source: Internet
AM stations are still marked on U.S. aviation charts In the early 1930s, single sideband and frequency modulation were invented by amateur radio operators. Source: Internet
As the amount of frequency modulation increases, the sound grows progressively more complex. Source: Internet
Early budget cards, such as the AdLib and the Sound Blaster and its compatibles, used a stripped-down version of Yamaha's frequency modulation synthesis (FM synthesis) technology Wiffen, Paul. Source: Internet
FM uses frequency modulation of the radio wave to reduce static and interference from electrical equipment and the atmosphere. Source: Internet
For the majority of researchers, the climbing fibers signal errors in motor performance, either in the usual manner of discharge frequency modulation or as a single announcement of an 'unexpected event'. Source: Internet
