A message signal of frequency 100 MHz and peak voltage 100V is used to execute amplitude
modulation on a carrier wave of frequency 300 GHz and peak voltage 400V. The modulation
index and difference between the two side band frequencies are:
Modulation Index -
The ratio of change of amplitude of carrier wave to the amplitude of original carrier wave.
- wherein
Side band frequency -
AM wave contains three frequency
- wherein
is carrier frequency, are side band frequency.
Band Width -
The two side band lie on either side of the carrier frequency at equal frequency intravel, fm
- wherein
Modulation index
