A carrier wave of peak voltage 20 V is used to transmit a message signal. For getting a modulation index of 60% , the peak voltage of the modulating signal is

A carrier wave of peak voltage 12 volts is used to transmit a signal. If the modulation index is 75%, the peak voltage of the modulating signal is

A carrier wave of peak voltage 12 Volt is used to transmit a message signal. Find the peak value of the voltage of the modulating signal in order to have a modulation index of 75%.

Write two factors justifying the need of modulating a signal. 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% ?
