In a modulator it is found that the amplitude spectrum consists a component at fc, the carrier frequency and one component each at fc - fs and fc + fs where fs is the modulating signal frequency. Then the modulator used is-A-AMB-AM or MBFM with modulation index 0.5C-FMD-PAM-B-AM or MBFM with modulation index 0.5
