RF modulator. An RF modulator (or radio frequency modulator) is an electronic device whose input is a baseband signal which is used to modulate a radio frequency source.
A ring modulator is an electronic device for ring modulation, used for amplitude modulation or frequency mixing. A ring modulator may be used as an effects unit (See #Use in music). It is referred to as ring modulation because the analog circuit of diodes originally used to implement this technique took the shape of a ring.
