Ring Modulator
A Ring Modulator is a device which takes two signals and multiplies them
together into one resultant signal
containing only the sum and difference
frequencies
of the two input waves. The original frequencies are
not
output!
However, every harmonic of each signal multiplies every other, according to its
amplitude. As a result, ring modulators tend to generate a lot of non-harmonic
frequencies which can sound very bell-like or out of tune.

This diagram shows the result of Ring Modulating two sine waves with frequencies of
200 Hz and 800 Hz. Only the Sum and Difference frequencies of 1000 Hz and 600 Hz
will result.
