DEVICE FOR MEASURING THE DURATION OF IMPULSES AND FREQUENCY OF OSCILLATIONS,

摘要

A device is described for measuring the length of impulses and the frequency of oscillations. It contains a differential circuit, a trigger, a unit of comparison, a cathode repeater, a circuit of discharge, a generator of impulses, a circuit of comparison, a reversing counter,and a step-type motor with a reducer. The device is distinguished by the fact that for the purpose of measuring and recording the length of micro-second single and periodic impulses between the output unit of comparison and the control switch (key) a storage integrating circuit and a slave multivibrator are included,extending the difference impulse by the time of the operation of the mismatching.
