Function of detector in demodulation
WebThis demodulator contains a square law device and low pass filter. The AM wave V 1 ( t) is applied as an input to this demodulator. The standard form of AM wave is. V 1 ( t) = A c … WebJan 4, 2024 · Conventional AM signals are easily demodulated by an envelope detector. It consists of a diode and an RC circuit, which is a simple low-pass filter as shown: During the positive half-cycle of the input signal, the diode conducts and the capacitor charges up to the peak value of the input signal.
