The latter is often a sine wave, but not necessarily ─ don't hesitate to try other waveforms if your ring modulator allows it, you will get very different results! The carrier wave can be any signal, simple or complex, depending on what the architecture of your synth allows. Its operating principle is based on a carrier wave (C) whose amplitude is modulated by a modulating wave (M). A ring modulator is, in fact, a series of diodes forming.a ring. The former takes its name from the structure of the electronic assembly that produces it. Ring modulation is an evolved form of amplitude modulation.
