This demodulation is …

Frequency Demodulation

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. WebJul 6, 2024 · This detector demodulates fm signals and suppresses amplitude noise without the need of limiter stages. Diodes CR1 and CR2 work as rectifiers. They block the negative part of the FM signal cycle. rok tips and tricks https://pisciotto.net
