Abstract:
A method of producing a transition-optimized DC-balanced sequence of characters from an input sequence of data blocks, said method including the steps of:receiving one input data block from said input sequence of data blocks, said input data block consisting of N bits, where N is a positive integer;generating a transition-optimized DC-balanced data block from said transition-optimized data block bydetermining the number of transitions between adjacent bits in the input data block and selectively performing an inversion operation on said input data block as a function of said determination in order to produce a transition optimized data block,determining a DC-balance of said transition optimized data block, comparing said DC-balance with a previously accumulated DC balance and selectively performing an inversion operation on said transition optimized data block as a function of said comparison, thereby creating said transition-optimized DC-balanced data block consisting of fewer than N+2 data bits.
