<p>PROBLEM TO BE SOLVED: To avoid discrimination of a synchronizing signal pattern for a period other than a synchronizing signal period even when a bit error is caused in reception data. SOLUTION: A bit comparison section 2 compares reception data D1 received serially and a synchronizing signal pattern D2 generated by a synchronizing signal pattern generating section 1 for each bit to provide an output of a comparison result. A mismatching bit number count section 3 counts the bit number mismatched by the bit comparison in the unit of synchronizing signal patterns. A mismatching bit number comparison section 4 reads number of preceding mismatched bits (k) stored in a bit number storage section 5 and compares it with a mismatched bit number (m) received newly and provides an output of a control pulse P1 when a new mismatched bit number (m) is smaller, and updates the stored value (k) in the bit number storage section 5 with the mismatched bit number (m). A synchronizing timing signal generating section 6 generates a synchronizing timing signal while changing the leading time in response to the control pulse P1.</p> |
