Demodulation is an important process in the reception of any amplitude modulated signals. Demodulation is the process by which the original information-bearing signal is extracted from the incoming overall received signal.
Once the signal is Modulated it is transmitted through the antenna and then this signal is received at the designated receiver. This received modulated signal has been to again demodulated to its original format by simply removing the carrier signal. This process is called demodulation. The Demodulator is actually an electronic circuit. The output of this message signal will give to the destination.
