The purpose of this circuit is to limit noise peaks on a radio receiver. The circuit is from an 80's documentation. The diode is commonly used and the circuit is applied to a receiver IF stage.
The circuit presented consists precisely of an oscillator (multivibrator) that takes advantage of the 4...
