Abstract
Abstract The position of one pulse relative to a reference pulse is obtained by hag the one pulse set a string of flip-flops until the setting is inhibited by a stop signal generated by the second pulse. The condition of the flip-flops is read by an encoded network.

Claim 1
Independent Claim
224 words
In a system for comparing a first pulse input, with a second pulse input with respect to time, the improvement comprising a plurality of incremental delay means connected to the first input; a series of settable gate means connected to said incremental delay means so as to successfully set said series of gate means in accordance to the travel of said first input through the incremental delay means; first connecting means connected between the second input and said series of settable gate means so as to inhibit any further setting of said gate means upon receiving a signal from said second input; encoding means connected to said series of settable gate means so as to indicate the condition of said settable gate means said series of settable gate means is a series of flip-flops; said incremental delay means having a series connection of delay devices each individually connected to a separate one of said series of flip-flops; first and second delay means; said first delay means being connected between said first input and said incremental delay means; said second delay means being connected between said second input and said series of settable gate means; and a pulser means connected to the output of the incremental delay means and connected to said encoding means so as to cause said encoded means to produce an output.
