SYNC. DETECTING CIRCUIT OF DIGITAL AUDIO INTERFACING FORMAT FOR OPTICAL CATV

摘要

a sync. bit detecting logic unit(4) for identifying the sync. bit data among the data which are read at a sync. bit interval; a sync. bit detection confirming unit(5) for rechecking whether the identified data are real sync. bit data or just signals having the sync. bit data pattern; and a sync. bit position estimation unit(9) for outputting the estimated sync. bit position to sync. bit detection confirming unit after loading by a sync. bit detecting confirming unit.
