What does DEMOD mean or stand for ?

A demodulator is an electronic device that is used primarily for two purposes – To extract the information signal from a carrier wave and in some cases to convert an analog into a digital signal so that it can be read and understood by a computer.

there are three main types of modulation – frequency modulation -FM, Amplitude modulation – AM and phase modulation PM.The DEMOD separates the original signal from these modulated waves and transfers the information to a device to be deciphered.

A MODEM is a device that can do both – upload and download data – meaning it can modulate as well as demodulate signals.
