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.
