Process and apparatus for the synchronization on reception of a signal provided with a synchronization pattern |
摘要 |
A process and apparatus for the synchronization on reception of a signal provided with a synchronization pattern. The process consists of retaining the synchronization setting until it can be readjusted on a periodically appearing potential synchronization pattern, optionally in the absence of a reference synchronization pattern corresponding to a previously acquired synchronization. The apparatus has a potential time base loaded to a given count during the presence of a potential synchronization pattern and a reference time base looped on itself and producing a synchronization signal when it reaches a given count. If a potential synchronization pattern is present in an iterative manner, a logic circuit produces a signal causing the synchronization change by loading the reference time base with the potential time base.
