Abstract
A circuit, indicating the first or last signal activated among n signals, includes flip-flops respectively associated with pairs of signals, a first signal of each pair being applied to a reset input of a flip-flop and a second signal of each pair being applied to a set input. Logic gates are respectively associated with each considered signal and are connected to indicate whether the considered signal is the first or the last activated signal when the flip-flops associated with all the pairs of signals including the considered signal are at respective suitable states once the first or last signal is activated.
