How do you calculate FM modulation index?

The FM modulation index is equal to the ratio of the frequency deviation to the modulating frequency.

How FM is generated from PM?

FM signals can be generated either by using direct frequency modulation, which is achieved by inputting a message directly into a voltage-controlled oscillator, or by using indirect frequency modulation, which is achieved by integrating a message signal to generate a phase-modulated signal, which is then used to ...

How do you find the frequency deviation of 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).
