PURPOSE:To obtain a reproducing frame synchronizing signal correcting the delay time difference of respective transmission paths by detecting a frame synchronizing signal in a data signal from the plural transmission paths, holding the frame synchronizing signal, obtaining the AND of those respective signals and generating the frame synchronizing signal for regeneration. CONSTITUTION:To the respective transmission paths, independent synchronous detecting circuits 1a-1c, frame temporarily storing circuits 2a-2c and synchronous holding circuits 4a-4c are provided. The synchronous detecting signals 1a-1c detect the frame synchronizing signal from a data transmission signal and this frame synchronizing signal is stored and held by the frame temporarily storing circuits 2a-2c for a constant time. These frame synchronizing signals, the AND is obtained by AND circuits 3a-3c and after that, the signals are outputted through the synchronous holding circuits 4a-4c as the reproducing frame synchronizing signal. |
