Physics Course/AM Modulation

Amplitude Modulation - AM
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
