Abstract
This invention relates to a repeater of a serial digital transmission system. The repeater comprises NRZI/NRZ converter, descrambler, scrambler and NRZ/NRZI converter. Data sent on a coaxial cable is input to a cable equalizer for attenuation characteristic compensation. The NRZI/NRZ converter receives the reception data through D-type flip-flop. Further, the NRZI/NRZ converter converts the reception data from NRZI code to NRZ code. The descrambler descrambles the data obtained by subjecting the reception data to a scrambling process represented by a generating polynomial. The scrambler scrambles the descrambled data output from the descrambler according to a scrambling process represented by the generating polynomial. The NRZ/NRZI converter converts the scrambled data output from the scrambler from NRZ code to NRZI code. A cable driver outputs the data onto the coaxial cable.
