Demodulation is extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio ) that is used to recover the information content from the modulated carrier wave. [ 1 ]
A demodulator (sometimes detector) is a circuit that performs demodulation, the inverse of modulation. A modem (from mod ulator– dem odulator), used in bidirectional communication, can perform both operations.
A major category of AM demodulation technique involves envelope detection, since the envelope of an AM signal is the original signal. The diode detector is a simple envelope detector. It consists of a diode connected between the input and output of the circuit, with a resistor and capacitor in parallel from the output of the circuit to the ...
A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio.
A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a local oscillator, hence the name. A product detector is a frequency mixer.

A demodulator is one of the most important parts of the receiver. The exact structure of the demodulator is defined by a modulation type. However, the fundamental concepts are similar. Moreover, it is possible to develop a demodulator that can process signals with different modulation types.
