Abstract
In a pulse counter-type FM detector circuit for obtaining audio signals at an output terminal by detecting FM signals in the following order through a limiter circuit, a trigger pulse generating circuit, a monostable circuit and an integrator connected to the output terminal where the monostable circuit comprises a gate circuit having at least two inputs where trigger pulses from the trigger pulse generating circuit are applied to a first one of the two inputs and a feedback signal to the other input, a differentiating circuit responsive to the output from the gate circuit, a differential inverter having a power supply and where the integrator includes an LC type low pass filter connected to the output side of the differential inverter circuit, the improvement comprising a terminal resistor connected between the power supply and the output terminal so that a part of the current flowing in the differential inverter circuit is diverted through the terminal resistor.
