ABSTRACT:
A digital circuit includes two digital signal sources, each having an output terminal connected to corresponding bus portions. Logic connects the two bus portions for propagating a signal pulse on one of the bus portions onto the other of the bus portion, and produces a digital indication signal signifying which of the signal sources generated the signal pulse. The logic includes logic gates, each having a first input connected to its corresponding bus portion, an output terminal connected to the indicator output, and a second input terminal connected to the output terminal of the opposite logic gate. The output of each logic gate also controls the connection of the other bus portion to a voltage source to bring that bus portion to the active state in response to the other bus portion being rendered active by its associated signal source.
