ABSTRACT:
The digital data transmission is of the type including the addition of clock and synchronizing information to the data to constitute the transmission signal, and the determination of the transmission speed from this received information. According to the invention, this information, in the transmission signal, comprises a synchronizing edge (SYNC) added to each group of N data bits (D0-D7, OP), and the determination of the transmission speed comprises producing N clock signals (CL0-CL9) from identical successive delays (480-489) of a synchronizing edge detected.
