Function of detector in demodulation
WebJul 24, 2009 · It is important to explore and to develop the new known signal demodulator based on neural network to enhance the quality of the communication system. And the method of changing the time sequential signal operation to parallel operation is highly valuable for developing new signal detection method and theory. WebThe DSB AM Demodulator Passband block demodulates a signal that was modulated using double-sideband amplitude modulation. The block uses the envelope detection method. The input is a passband representation of the modulated signal. Both the input and output signals are real scalar signals.
