Question

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%?

Answer 1

modulation is must so that size of transmitting antenna is small

modulation is must so that mixing up of signals does not take place .

v/12 =75/100

v=75×12/100

=7.5×1.2=9 volt
