6b/8b encoding
text:
In telecommunications, 6b/8b is a line code that expands 6-bit codes to 8-bit symbols for the purposes of maintaining DC-balance in a communications system. The 6b/8b encoding is a balanced code --
each 8-bit output symbol contains 4 zero bits and 4 one bits. So the code can, like a parity bit, detect all single-bit errors. The number of 8-bit patterns with 4 bits set is the binomial coefficient = 70. Further excluding the patterns 11110000 and 00001111, this allows 68 coded patterns: 64 data co
