The Total solution for NCERT class 6-12
A carrier wave of peak voltage 12┬аV 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,┬аAc┬а= 12 V
Modulation index,┬аm┬а=75% = 0.75
Amplitude of the modulating wave =┬аAm
Using the relation┬аformodulation index:
