Equation of an AM wave: V = 10(1 + 0.05 sin 5000t) sin (6.28 xx 10^(6)) t volt Find the voltage amplitude and frequency of the carrier wave, frequency of the data signal and the modulation index.

A wave is represented as e=10 sin (10^(8)t+6 sin 1250t) then the modulating index is

Modulation is a process employed to superimpose a carrier wave with a signal wave. A message signal of frequency 10 KHz and peak voltage of 10 volts is used to modulate a carrier wave of frequency 1 MHz and peak voltage of 20 volts.Determine the modulation index and frequencies of side bands.
