Define modulation index. Why is its value kept in practies, less than one ? A carrier wave of frequency 1.5 MHz and amplitude 50 V is moduclated by a sinusoidal wave of frequency 10KHz producing 50% ampitude moducation. Calculate the amplitude of the AM wave and frequencies of the side bands produced.
