It is also suggested the change for use as SSB detector, but it is an old device and the circuit has more interest as a reference IF level is supposed to be maximum 50mV RMS. MC1351 should not have ...

The demodulator circuit board is stacked on top of the power supply in the box to save space. (Click to enlarge photo) On my bench, I’m lucky enough to have a classic Orban 8000, and sending through ...

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 ...

inhibit function differs For the 74HCT4046A, logic 1 at the inhibit input (pin INH) disables the vco and demodulator, while logic 0 turns both on. For the 74HCT9046A, logic 1 on the inhibit input ...

4 x 80W into 4Ω at 25V with 10% THD at 1kHz The output LC filter is included in the feedback loop to iron-out the characteristics of the demodulation circuit. “Regardless of the big phase shifting ...
