Abstract
Abstract In a monostable multivibrator including a gate circuit having first and second inputs, a differentiating circuit responsive to the output of the gate circuit and a voltage comparison circuit responsive to the output of the differentiating circuit where the gate circuit is adapted to have a trigger pulse applied to the first input thereof and the output of the voltage comparison circuit fed back to the second input thereof, the improvement in the monostable multivibrator of means for setting the reference level of the trigger pulse at the first input lower than the reference level of the output of the voltage comparison circuit fed back to the second input of the gate circuit.
