PROBLEM TO BE SOLVED: To provide a signal-transition discriminator having a function early discriminating a signal to be particularly detected and noises including even the transition time of the signal regarding a signal detector.;SOLUTION: The signal-transition discriminator has a discriminating means discriminating a regular input signal, and a set control means setting and controlling a signal-transition pattern to the signal discriminating means by comparing the transition-time characteristics of an input signal to the discriminator with the signal-transition pattern changed into a signal pattern.;COPYRIGHT: (C)2006,JPO&NCIPI
