The Total solution for NCERT class 6-12
A carrier wave of peak voltage 12 V is used to transmit a message signal.What should be the peak voltage of the modulating signal in order to have amodulation index of 75%?
Amplitude of the carrier wave, Ac = 12 V
Modulation index, m =75% = 0.75
Amplitude of the modulating wave = Am
Using the relation formodulation index:
