ABSTRACT:
A system for measuring the difference in time between two unknown signals utilizing a pair of matched delay lines with taps which are differentially separated in time. Each pair of output taps from the two delay lines is fed to a dc flip flop or other sensor which determines which of the two inputs occurs first in time. When there is a transition in the sequence of input signal timing a ROM determines the particular pair of taps which provided that change in sequence and delivers a series of least significant bits representative thereof.
