A circuit for detecting the relative time of occurrence of first and second signals applied to first and second terminals includes a pair of bistable flip-flops. In response to the occurrence first of the first signal the first one of the flips-flops is set to initiate the generation of a control signal. A time delay responds to the control signal and upon expiration of the time delay interval the second one of the flip-flops is set and this in turn resets the first flip-flop to terminate the control signal. In response to the first occurrence first of the second signal the second one of the flip-flops is set and this inhibits the setting of the first flip-flop. In the event that the first and second signals occur simultaneously the second flip-flop sets quickly resetting the first flip-flop. In response to either signal, a conductive path is established between the terminals.
A circuit for detecting the relative time of occurrence of one signal among a plurality of signals and generating a control signal in response to the occurrence first of a first one of the signals, each signal being connected to at least one of a plurality of circuit inputs, the circuit includes means responsive to the level of said first signal for generating the control signal, means responsive to the occurrence of a second one of said plurality of signals for inhibiting the control signal generating means in response to the subsequent occurrence of said first signal, the improvement.
