It’s most often seen for AM band receivers ... but it’s a circuit which also works at much higher frequencies. [Perian Marcel] has done just this, with a regenerative receiver for the FM ...

While most regenerative receivers are designed for AM broadcasts ... most advanced receiver ever conceived, and it certainly isn’t the most sensitive. But it’s one of those circuits that ...

Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator generates a signal 455 kHz less than the frequency of the ...
