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 fre-
quencies 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 800 Hz and 200 Hz.
Only the Sum and Difference frequencies of 600 Hz and 1000 Hz will result.
There are no controls on the ring modu-
lator as shown by the block diagram
below. The left and right outputs are
simply multiplied together to form a
monophonic output.
