Transition-controlled digital encoding and signal transmission system

摘要: A method and apparatus for producing a transition-controlled, DC-balanced sequence of characters from an input data bytes is disclosed herein. The bits in each the are selectively complemented accordance with number logical transitions byte order to produce blocks. cumulative disparity then determined between values different type included within ones blocks previously encoded into characters. In addition, current candidate character associated one being also determined. assigned if polarity opposite first disparity. Alternately, complement polarity. high-transition mode operation, including less than minimum so that such block includes excess transitions. low-transition having more predefined maximum
