This great overview has given me a better insight into the exact intended functions, such as that of the L3 choke, of the circuit elements, as well as into some important considerations in choosing component impedances. Thank you very much.
This is the FM demodulation "discriminator" circuit. It is one of the simplest analog demod setups one could think of. An RF (FM) voltage signal is applied at V12 and the voltage at ' a' ' is supposed to contain the AF signal in its amplitude.
The idea behind the circuit is that it resonates at...
