Below is a picture of how two simple sinewave signals are used for amplitude and ring modulation
As you can see in the figures above, the main practical difference between amplitude- and ring modula-
tion is the sideband amplitudes and the appearance of Oscillator 1’s original signal in the frequency spec-
trum. Another difference is that the resulting ring modulation signal phase-shifts 180 degrees every half
modulator (Oscillator 2) period. The amplitude modulated signal doesn’t phase-shift.

If more complex waveforms are used for amplitude- or ring modulation, sidebands will be generated for
each partial of the signal.
