SIGNAL TRANSMISSION SYSTEM

摘要

PURPOSE:To detect surely a synchronism code series by providing continuously plural synchronism code series of the same content in a packet. CONSTITUTION:The packet includes n-set of synchronism code series (m-bit) the same content as a significant data and transmitted to a serial/parallel converting section 2 and a gate signal generating section 6 as a serial signal 1. The converting section 2 forms the synchronism code series in m-bit as parallel data 3-1-3-m and transmits it to a synchronism code deciding section 4, which brings a synchronism code detecting signal 5 to an H level when the series is coincident with a correct synchronism code series stored therein. The gate signal generating section 6 counts the packet from the start part by 0, m, 2m,...(n-1)m-bit and gate signals 7-0-7-(n-1) are outputted. A synchronizing signal generating section 8 obtains a detection signal 5 and a synchronizing signal 9 from the gate signals 7-0-7-(n-1) and outputs it.
