An AM wave expression consists of carrier and two sidebands. The carrier component of the modulated wave has the same amplitude as the unmodulated carrier. The AM modulated wave contains extra power in the two sideband components. The amplitude of the sidebands depends on the modulation index ‘ma‘. Therefore the total power in the modulated
