Abstract

PURPOSE: To improve measurement accuracy by simple constitution by separating horizontal synchronizing pulses from a video signal and then by detecting variation in time interval in the form of the jitters at this time.
CONSTITUTION: A video signal is synchronously separated 1 and from its output signal, horizontal synchronizing pulses are extracted through equivalent vertical pulse removal 2; after 1st and 2nd horizontal synchronizing removal operations 3 and 4, an output from 1st removal circuit 3 is integrated and the peak value a voltage integrated by peak holding circuit 7 is held to detect the jitters as a voltage value. Namely, charging gate circuit a turns ON charging switch S2 after discharging switch S1 turns ON and OFF, and horizontal synchronizing pulses from circuit 3 are integrated 5 as long as the time in proportion to its pulse interval. Then holding gate circuit 10 performs peak holding 7 of the peak value of an integral value with holding switch S3 ON and detects and jitters as a voltage, thereby improving measurement precision by simple constitution.
