Encoding Schemes
| Code Name | Binary Code | Code Definition |
|---|---|---|
| NRZ-L | ![]() | Non-Return-to-Zero Level "One" is represented by one level "Zero" is represented by another level lower the one but not zero. |
| NRZ-M | ![]() | Non-Return-to-Zero Mark "One" is represented by a change in level "Zero" is represented by no change in level. |
| NRZ-S | ![]() | Non-Return-to-Zero Space "One" is represented by no change in level "Zero" is represented by change in level. |
| NRZ-I | ![]() | Non-Return-to-Zero Inverse "One" is represented by no change in level "Zero" is represented by change in level. |
| Bi-Phase-L | ![]() | Bi-Phase Level (Split Phase) Level change occurs at the beginning of every bit period "One" is represented by a "One" level with transition to the "Zero" level "Zero" is represented by a "Zero" level with transition to the "One" level. |
| Bi-Phase-M | ![]() | Bi-Phase Mark Level change occurs at the beginning of every bit period "One" is represented by a midbit level change "Zero" is represented by no midbit level change. |
| Bi-Phase-S | ![]() | Bi-Phase Space Level change occurs at the beginning of every bit period "One" is represented by no midbit level change "Zero" is represented by a midbit level change. |
| DBi-Phase-M | ![]() | Differential Bi-Phase Mark Level change occurs at the center of every bit period "One" is represented by no level change at the beginning of the bit period "Zero" is represented by a level change at the beginning of the bit period. |
| DBi-Phase-S | ![]() | Differential Bi-Phase Space Level change occurs at the center of every bit period "One" is represented by a level change at the beginning of the bit period "Zero" is represented by no level change at the beginning of the bit period. |
