Amplitude Modulation Synthesis

Amplitude Modulation (AM) creates a new partial in the spectrum of input sources. This added partial is called sideband. This is because the sum and difference of the input source are these frequencies. Amplitude modulation creates complex partial structure, especially non-harmonics, which result in metallic sounds. If the input waveform was A, B,

 

A = 110 Hz

B = 74 Hz

A + B = 185 Hz

A - B = 35 Hz
