FM
Frequency modulation varies the carrier’s instantaneous frequency. Deviation and the highest modulation frequency influence the required bandwidth.
Also found under: Frequenzmodulation · Frequency Modulation
A concrete example
Narrowband voice FM requires different filter settings from a wideband FM broadcast signal.
What to keep in mind
An FM demodulator does not turn DMR or D-STAR into ordinary intelligible speech.
