Question

What will be the changes in FM wave when the
amplitude of the modulating signal in increased ?​

Answer 1

Answer:

Specifically, the higher the amplitude of the information signal, the greater the frequency change. The actual carrier frequency deviates above and below the center carrier frequency as the information signal amplitude varies.

Explanation:

Answer 2

Answer:

Also in AM if the amplitude of modulation is to be increased, the power must be increased proportionately. In FM the amplitude of the frequency modulation can be increased without increasing the power at all.
