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 demodulator is a circuit used in AM (amplitude modulation) and FM (frequency modulation) receivers to separate the information that was modulated onto the carrier from the carrier itself.It could be audio and/or video information, or other data. A demodulator is the analog of the modulator. A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination.   For many years the modulated carrier wave was converted to a radio signal.
