Physics Course/AM Modulation

Amplitude Modulation - AMEdit

In AM Modulation sound wave is enveloped and mixed with high frequency carrier wave such that the amplitude of the carrier wave varies with sound wave's amplitude . In general , AM wave is easy to be interfere with other sound waves in the medium travel through therefore the quality of sound is not very goog . AM sound wave cannot travel very far . AM wave is usually use to transmit sound in local area
