Amplitude Detection - The process of demodulation demands that the modulated wave has some definite average value and the carrier wave
The process of demodulation demands that the modulated wave has some definite average value and the carrier wave is separated out. Hence in demodulation of an AM wave two operations, viz. rectification of the modulated wave and elimination of the RF component of the modulated wave are involved.
