The ratio of peak value of modulated signal to peak value of carrier signal is

For an amplitude modulated wave message signal peak voltage = 20V carrier signal peak voltage = 20V. What is modulated index.

A message signal is used to modulate a carrier frequency. If the peak voltages of message signal and carrier signals are increased by 0.1% and 0.3% respectively, then

Three amplifiers with voltage gains 10 ,20 and 30 are connected in series . If the input signal has a peak value of 1 mV then the peak value of the ouptut voltage is

A carrier wave of peak voltage 10 V is used to transmit a message signal. The peak voltage of the modulating signal in order to have a modulation index of 80% is

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

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

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