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. WebApr 22, 2024 · It's designed to produce the mixer frequency and do the IF FM demodulation (or produce an IF mixer frequency for SSB demodulation) in one chip, so if you've already got a superhet stage you could replace part of it with that. There should be similar ICs which can work directly in the HF band. – Chromatix Apr 22, 2024 at 21:23 siam brass flatware set

Recall that any wave has three basic properties: 1) Amplitude – the height of the wave 2) Frequency – a number of waves passing through in a given second 3) Phase – where the phase is at any given moment. There are different strategies for modulating the carrier wave.
