A sinusoidal carrier voltage of frequency 1200 kHz is amplitude modulated by a sinusoidal voltage of frequnecy 20 kHz. The maximum and minimum modulated carrier amplitudes of 100 V and 90 V are produced. Calculate the frequency of lower and upper side bands, unmodulated carrier amplitude, modulation index and amplitude of each side band.
