Not only is the composite demodulation described in this article useful as a confidence check and troubleshooting aid, but in the age of FM translators for struggling AMs, the convenience of having ...

The carrier frequencies for AM operate from 530 kHz to 1610 kHz. Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator ...

This circuit solves the problem of sending data over a cable with no free conductors. The data is OOK (on-off keying) modulated and superimposed on a high-frequency carrier so ...

Because the network in the modulator circuit has two floating differential outputs, the demodulator network requires two floating sources. The simplest way to accomplish this requirement is by using ...

That’s because this demodulator is about as close to a direct translation between a vacuum tube circuit and a silicon circuit as possible.
