WebNarrowband FM, NBFM often uses deviation figures of around ±3kHz or possibly slightly more. If quality is not as important for radio communications applications, the much narrower bandwidth has advantages in terms of radio spectrum efficiency. Wideband FM: Wideband FM is defined as the situation where the modulation index is above 0.5. WebWith FM, it is the spectrum of the integral of the baseband signal that appears in the band surrounding the carrier frequency. For the single-baseband-frequency, m-equals-1 modulation shown above, we have the following: The next spectrum is with m = 4:
