WebBy using two amplitude demodulators driven by carrier-frequency sinusoids with a 90° phase difference, we generate two different baseband signals that together can convey information encoded via changes in the received … WebIn this system, a voltage controlled oscillator (VCO) is phase locked by a feedback loop, which forces the VCO to follow the frequency variations of the incoming FM signal. The low-frequency error voltage that forces the VCO's frequency to track the frequency of the modulated FM signal is the demodulated audio output.
