The amplitude modulation as well as demodulation of an electromagnetic wave in a transversely magnetised piezoelectric semiconductor plasma has been studied in different wave number regions over a wide range of electron cyclotron frequency.doi:10.1016/0375-9601(80)90673-8S. Guha...
2. In demodulation, signals from the transmitter enter the demodulator and are divided into two signals that are sent into separate mixers. The local oscillator generates needed frequency demodulation signals, which are in-phase and quadrature signals. View Quadrature Amplitude Modulation: Modulator ...
