PURPOSE:To fetch a suitable data less in data error by performing parity check by a parity bit of the next unit when a synchronizing signal before one unit is detected. CONSTITUTION:The system consists of a parity check means performing the parity check of a digital signal transmitted in the next unit by using a patity bit of the next unit of a detected synchronizing signal when the synchronizing signal before one unit is detected at synchronizing signal detecting circuits 43- 46, and a circuit means fetching at least data among digital signals after parity check, when the detecting signal of the synchronizing signal of the same unit as the digital signal performed for the parity check by the parity check means from the circuit 43-46 and the signal representing matching of the parity is extracted from the parity check means. Thus, the fetching of erroneous data is decreased and the confirmation of data is executed easily. |
