ABSTRACT:
A Gray code decoder for decoding input numbers includes a first select circuit that selects an M-bit Gray code number from a M-bit Gray code having a one-bit separation I and a two-bit separation J. A second select circuit selects an 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, 2N. A concatenate circuit concatenates the selected M-bit Gray code number and the selected N-bit Gray code number to produce a K-bit Gray code number.
