Abstract

A circuit for eliminating pulses of a minimum predetermined period including a pulsed current source for charging an integrating capacitor, the potential of which is sensed by a threshold detecting circuit. The connection between the current source and the integrating capacitor is selectively controlled by a pair of complementary field effect transistors responsive to the signal including the narrow pulses. The minimum pulse width is determined by a number of device design parameters as well as an externally applied oscillation frequency.
