AM Demodulator for Intercom Schematic Circuit Diagram
https://circuit-diagramz.com/demodulator-intercom-schematic-circuit-diagram/
AM Demodulator for Intercom Schematic Circuit Diagram. This circuit should be considered as more of an experimental circuit for AM demodulation, than as a practical application. In the associated ‘AM modulator’ we have raised the problems caused by mains hum, getting in the way of interference-free operation of the AM mains intercom.

output of the DDC provides the demodulated audio to the D/A converter, and the Q output of the DDC is used to build a simple phase-locked loop (PLL) to synchronize the HFO to the incoming AM signal carrier. The circuitry added to create the PLL is shown in Fig 4. September QEX: A Simple Synchronous-AM Demodulator - Page 3

TBA120 Demodulator Circuit. P. Marian. The TBA120 Series ICs provide a high-gain limiting IF amplifier and a quadrature coincidence detector in one package. These ICs are primarily intended for extraction of TV intercarrier sound, which (in Europe) is frequency modulated onto a 5.5MHz or 6MHz subcarrier. The TV waveform constitutes an extreme ...
US4361813A - FM Audio demodulator with dropout noise ...
https://patents.google.com/patent/US4361813A/en
A previous level holding circuit is connected to an output of an FM demodulator to eliminate dropout disturbance from a reproduced audio signal from a record medium on which an FM-modulated audio signal has been recorded. The previous level holding circuit is controlled by an output of a circuit for detecting dropout in the reproduced signal and comprises a gate circuit …
Circuit Design: How to Demodulate AM Signal

The Demodulator circuit is connected to an amplifier through a 47K ohm resistance so as to avoid the loading effect of the weak signal by the input of the amplifier circuit. This circuit uses a NPN transistor BC548 which has a very good current gain with a base current limiting resistor and a collector resistor.

• Implementing an amplitude demodulator with a product detector. Experiment: a) Modulation The circuit of Figure 1 shows an AM modulator circuit, whose carrier and audio signals are single-ended inputs, carrier to pin 10 and audio to pin 1. The gain of entire circuit is determined by the R8 value. The R9 determines the amount of bias current.
