  • Apparatus and method for encoding data in a fiber data distributed interface (FDDI)
    Patent number: 5655078
    Abstract: A fiber data distributed interface (FDDI) system uses an MLT3A encoding scheme in order to reduce DC bias or baseline wander. The MLT3A encoding scheme is a scheme wherein logical zeros are transmitted as ground voltages and logical ones are transmitted as one of either positive voltages or negative voltages depending upon past transmission history (FIG. 4 ) wherein the past history is recorded by a counter C or an analog circuit. MLT3A ensures that the baseline wander or DC bias returns to zero or is maintained as close to zero as possible in a timely manner so that no FDDI systems will fail from baseline wander.
