PLL FM Demodulator – Simple Circuit Diagram For this example, an FM signal consisting of a 10 kHz carrier frequency was modulated by a 400 Hz audio signal. The schematic diagram shows the connections of the CD4046B as an FM demodulator. The total FM signal amplitude is 500 mV, therefore, the signal must be ac coupled to the signal input (terminal 14). Simple Fm Demodulator Circuit Diagram | Electronic Circuit ... How to Build a Simple Fm Demodulator Circuit Diagram. This is a Simple Fm Demodulator Circuit Diagram. The NE564 is used as an FM demodulator. The connections for operation at 5 V and 12 V are shown in Figures 21 4A and 21 4B. The input signal is ac coupled with the output signal being extracted at Pin 14. Demodulator – Simple Circuit Diagram This is a linear FM detector circuit. This circuit usually is used in telemetry applications and wide range of analog communications. The main part of this circuit is a XR 2211. This circuit has an external buffer amplifier that is needed due to the high impedance output at pin 11 of XR 2211. This circuit also has a post detection filter Rf Cf. Demodulator – Page 2 – Simple Circuit Diagram We can simply a rectifier using a linear detector. It’s not only have no gain, but also no distortion. An example from two op amps is the easy one as shown in the following circuit diagram. The second op amp is a precision half wave rectifier (the second diode is to “catch” the op amp on the other half cycle and prevent it from saturating). PLL FM demodulator circuit using XR2212 . Design, working ... A simple PLL FM demodulator circuit using IC XR2212 is shown here. XR2212 is a highly stable, monolithic PLL (phase locked loop) IC specifically designed for communication and control system applications.
