ABSTRACT:
A signal transition detection circuit comprises a decoder circuit (1) for decoding a plurality of signals, a delay circuit (2) having a rise delay time period (T.sub.r) and a fall time period (T.sub.f) which are different from each other, and a logic circuit (3). The logic circuit performs a logic operation upon the outputs of the delay circuit to generate a pulse signal (ATD) for indicating at least one transition of the signals.
