The DC component of the FM demodulator is supplied to the comparison circuit (comparator), is performed on four low-power silicon transistors! for example, KT315, KT361, and two LEDs АЛ102А—АЛ102В (see figure).
With the engine variable resistor R5 on the right shoulder of the comparator serves a reference voltage from a stabilized power supply.
