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 a modulation index of 75%?
Given: The peak voltage of the carrier wave is, Ac=12 V Modulation index, m=0.75 The peak voltage for the modulating signal is given by: m=AcAm. Am=0.75×12 So, Am=9 V
