Abstract

PURPOSE: To obviate the effect of noise by providing a means of extending the discharge time constant of the first stage capacitor and a means of discharging before the charge potential of the second stage capacitor reaches a reference potential.
CONSTITUTION: A constant current source i2 which performs discharging of a first capacitor C1 and a switch circuit Q which is started by the output having taken the NOR of an input pulse IN and the output of a comparator CMP 1 are newly added and connected. In the period of Ti2, the capacitor C1 discharges and the capacitor C2 starts charging. When there are no more input pulses before the curves of both potentials Vc1, Vc2 intersect at a certain critical point and the capacitor C1 begins to discharge, the capacitor C2 is reset before its potential reaches a reference potential ES and therefore the output of a discrimination circuit SNS is not transmitted.
