ABSTRACT:
A method of encoding n-bit information words into m-bit code words and the other way round is described, which code words have a specific disparity d and a digital sum value which is limited to values p and q. In order to enable encoding and decoding without the use of an extensive look-up table, use is made of a series of numbers which is a modified version of numbers in conformity with the Newton binomial. By means of this modified series, the n-bit information words, which are arranged in conformity with their binary weights, are mapped lexicographically and unambiguously onto code words with said limitations, and the other way round.
