Abstract

본 발명은 바이폴라 코딩과 디코딩방법을 공개한다. 그 코딩방법은 기준레벨에서 제1레벨로 천이하는 것을 제1데이타로 코딩하고 상기 기준레벨에서 제2레벨로 천이하는 것을 제2데이타로 코딩하는 것과 제1레벨에서 기준레벨로 천이하는 것을제1데이타로 코딩하고 제2레벨에서 상기 기준레벨로 천이하는 것을 제2데이타로 코딩하는 방법이다. 디코딩 방법은 제1데이타를 기준레벨에서 제1레벨로 천이하도록 디코딩하고 제2데이타를 기준레벨에서 제2레벨로 천이하도록 디코딩하는 것과 제1데이타를 제1레벨에서 기준레벨로 천이하도록 디코딩하고 제2데이타를 제2레벨에서 기준레벨로 천이하도록 디코딩하는 방법이다. 따라서, 별도의 코딩과 디코딩회로가 필요없으며 지터도 감소시킬 수 있다.The present invention discloses a bipolar coding and decoding method. The coding method includes coding a transition from the reference level to the first level with the first data, coding the transition from the reference level to the second level with the second data, and transitioning from the first level to the reference level. A method of coding with data and coding with second data is a transition from the second level to the reference level. The decoding method includes decoding the first data to transition from the reference level to the first level, decoding the second data to transition from the reference level to the second level, decoding the first data to transition from the first level to the reference level, and It is a method for decoding two data to transition from the second level to the reference level. Thus, no coding and decoding circuitry is required and jitter can be reduced.

Claims

In the bipolar coding method, a bipolar coding method is characterized in that the transition of the absolute size from the reference level to the first level is performed with the first data and the bipolar coding is performed from the reference level with the absolute size transitioned to the second level. Coding method.

The bipolar coding method of claim 1, wherein the first level has a lower absolute potential than the second level.

A bipolar coding method, comprising: coding a transition from a first level to a reference level with first data and coding a transition from a second level to the reference level with second data.

4. The bipolar coding method of claim 3, wherein the first level has a lower absolute potential than the third level.

A bipolar decoding method, comprising: decoding a first data so that an absolute size transitions from a reference level to a first level and decoding the second data so that an absolute size transitions from a reference level to a second level.

6. The bipolar decoding method according to claim 5, wherein the first level has a lower absolute potential than the second level.

A bipolar decoding method comprising: decoding a first data so that an absolute size transitions from a first level to a reference level and decoding a second data so that an absolute size transitions from a second level to a reference level.
