Circuit system suitable for codifying NRZ type binary signals into CMI type binary signals

摘要

A circuit system suitable for codifying NRZ type binary signals into CMI type binary signals includes a plurality of bistable means, an EXOR type logical gate, a presynchronization device and a combinatory logic device capable of creating a CMI type binary signal by codifying with an identical circuit path the "1" bits and "0" bits, sequence of bit present in the NRZ type binary signals.
