Abstract

A unique word detecting apparatus comprising a preamble code detecting circuit 202 for detecting a preamble code PR to be transmitted before the unique word UW, a unique word detecting circuit 204 for holding in advance the data of the unique word UW to be detected, an error detecting circuit 203 for comparing the external data with the unique word UW successively bit by bit only when and after the preamble code PR is detected and for outputting an error signal E when not coincide, and a unique word detecting circuit 204 for counting the number of outputs of the error signal E and for outputting a detecting signal DT indicating that the unique word UW has been detected when the count value is equal to or smaller than a predetermined value. Only when the preamble code PR transmitted before the unique word UW is detected, the external data ED is compared with the unique word UW successively bit by bit, the number of uncoincident bits is counted, and when the count value is equal to or smaller than a predetermined value, the detecting signal DT indicating that the unique word UW has been detected is outputted.
