To illustrate what ring (balanced) and amplitude modulation can do to a sound, we have created an ex-
ample with three sine waves, one carrier and two different modulators (Ring (Balanced) and Amplitude
(Unipolar)). The graphs to the left show the amplitude as a function of time, and to the right the ampli-
tude as a function of the frequency.
