Step-by-step solution

A carrier wave of peak voltage 16 ~V is used to transmit a signal. If the modulation index is 75 % , the peak voltage of the modulating signal is 12 ~V . Explanation: Modulation Index ( MI )= Peak voltage of modulating signal ( V _ m ) Peak voltage of carrier signal ( V _ C ) Given, Ml =75 % and V _ C =16 ~V V _ m = MI V _ c = 75 100 16=12 ~V
