NUMERICAL DISPLAY DISTORTION METER

摘要

A numerical display distortion meter for signals featuring amplitude transitions at instants characteristic of the data embodied in the signals includes first and second counters of clock pulses, reset means responsive to the transitions in the distorted signal for resetting the first counter only if its count exceeds half its capacity and for resetting said second counter only if its count is less than half its capacity, and means for determining the time difference between the counts in said first and second counters at the end of an operation cycle.
