Separation enhanced gray codes

摘要

In general, in one aspect, the invention features a Gray code decoder for decoding input numbers according to a K-bit Gray code and a Gray code encoder for encoding input numbers according to the K-bit Gray code. The K-bit Gray code is constructed from a M-bit Gray code having a one-bit separation I and a two-bit separation J and a N-bit Gray code number from a N-bit Gray code, wherein K=M+N, M>=N, and at least one of I and J is greater than, or equal to, 2^N.
