How do you find the maximum frequency deviation?

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 maximum frequency deviation?

The FM broadcasting range, which is always between 87.5 and 108 MHz, uses a typical channel which spans from 100 kHz to 200 kHz, with a maximum frequency deviation of 75 kHz. This deviation of 75kHz can be both negative as well as positive.

What is the maximum frequency deviation of the modulated signal?

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.

What is the phase deviation?

The peak difference between the instantaneous phase angle of the modulated wave and that of the sine-wave carrier.
