In AM, the cent percent modulation is achived when

A

Carrier amplitude = signal amplitude

B

Carrier amplitude `!=` signal amplitude

C

Carrier frequency = signal frequency

D

Carrier frequency `!=` signal frequrancy

Text Solution

Verified by Experts

The correct Answer is:
a
When signal amplitude is equal to the carrier amplitude, the amplitude of carrier wave varies between `2A` and zero.

`m_(a)=("Amplitude charge of carrier")/("Amplitude of normal carrier")=(2A-A)/(A)xx100=100%`
