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

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

A message signal of frequency 10 kHz and peak voltage 5V is used to modulate a carrier of frequency 100 kHz and peak voltage of 20 V. Determine The side bands.

A message signal of frequency 10 kHz and peak voltage 10 volt is used to modulate a carrier of frequency 0.5 MHz and peak voltage 100 volt. Determine (i) modulation index (ii) the side bands produced.

A message signal of frequency 12 kHz and peak voltage 12 volt is used to modulate a carrier of frequency 1 MHz and peak voltage 24 volt. What is the modulation index and the side bands produced ?
