The FM broadcasting range between 87.5 and 108 MHz uses a typical channel spacing of 100 or 200 kHz, with a maximum frequency deviation of +/-75 kHz, in some cases leaving a buffer above the highest and below the lowest frequency to reduce interaction with other channels.

How do you measure frequency deviation in FM?
f(t) = f0 + ∆f(t) Peak deviation: In the case of frequency modulation, the peak deviation ∆f is the absolute maximum of the difference between the unmodulated carrier frequency (f0) and the instantaneous frequency f(t).
What is frequency deviation in FM?
Frequency deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency. The FM signal's instantaneous frequency changes with time around the carrier frequency ω ω ω C .
What is the minimum frequency deviation for the FM signal?
From the question, we know that the frequency deviation in a FM transmission is δ=18.75kHz . We know that the nature of broadcast of the given frequency band 88- 108 MHz is FM radio. The commercial FM broadcasting uses a maximum modulating frequency of 75 kHz and minimum modulating frequency of 15 kHz.
What is frequency deviation formula?
The toned (single frequency) modulating signal consists of only one frequency component and this signal is modulated with a carrier signal. For tone modulation, the frequency deviation is. ∆ f = k f A m. Where, A m is the amplitude of modulating signal.
