Another standard point of that parallel circuit\r\n connected with two resistors (100kΩ, 1kΩ) in collection. A capacitor is \r\nconnected with the well-liked point of resistors (100kΩ, 1kΩ). A capacitor \r\nis linked in sequence with base of the transistor and the pin number 1 \r\nof the ZN414.
One finish of the 10kΩ resistor is connected with the collector level of the transistor BC549 and every other finish is connected with the ability provide +Vcc.
And\r\n one end of the 100kΩ resistor is hooked up with the collector and \r\nanother finish connected with base. 105pF capacitor is hooked up between \r\ncollector and ground. Pin three of IC ZN414 and emitter of the transistor is connected to the ground.
