Question

Define modulation factor in amplitude modulation.

Answer 1

It is defined as the ratio of change of amplitude in carrier wave after modulation to the amplitude of the unmodulated carrier wave.

Modular factor $m$$=\frac{\text{Amplitude change of carrier wave after modulation}}{\text{Amplitude of carrier wave before modulation}}$

$m=\frac{\text{Signal Amplitude}}{\text{Carrier Amplitude}}$.
