An apparatus for accurately detecting a start pattern in the event of reception of a digital signal in which the start pattern is followed by an information signal. The detection of a start pattern is performed only once while a start pattern is received so that, although a pattern analogous to the start pattern may be included in a data signal, a pattern match output is prevented from responding any further despite such a pattern. Even a start pattern having an extremely great length is detected without errors. |
