Question

A carrier wave of peak voltage 14 V is used for transmitting a message signal. The peak voltage of the modulating signal given to achieve a modulation index of 80 % will be:, 22 .4 V, 7 V, 11 .2 V, 28 V

MARKS App · Accepted Answer

Modulation index, m = A m A c ⇒ A m = 0.8 × 14 = 11 .2 V
