Abstract

PURPOSE: To reduce the distortion factor of a demodulation signal, by turning on one of an NPN transistor (TR) and a PNP TR at charging/discharging of capacities of a capacitor and an LPF, in an output circuit of an FM demodulation circuit of a pulse count system.
CONSTITUTION: Amplified pulses are supplied to both the bases of TRs Q22, Q23, and when a TRQ21 is nonconductive, the TRQ22 is conductive and a capacitor C22 and a capacitance of an LPF21 are charged. On the othe hand, when the TRQ21 is conductive, the TRQ23 is conductive and the capacitor C22 and capacities of the capacitor C22 and an LPF are discharged.
