A circuit for detecting leading or lagging phase relationship between first and second two-level input signals at each level transition of a selected one of the input signals and comprising first and second Exclusive OR gates each having first and second input terminals and a single output terminal and each responsive to signals of equal and non-equal logic levels supplied to the first and second input terminals thereof to produce an output signal having high and low logic levels, respectively. Further connections supply the first and second input signal...


1. A circuit for determining the leading or lagging phase relationship between first and second two-level signals at each level transition of said first two-level signal, and comprising: first and second Exclusive OR gate means each having first input terminals for receiving said first and second two level signals respectively and further having a second input terminal and an output terminal; decoding means having first and second input terminals coupled respectively only to the output terminals of said first and second Exclusive OR gate means and re...
