Generating a Gray code sequence for any even length using an intermediate binary sequence

摘要

Generating Gray sequences for non-standard sequence lengths to be used in cyclical sequences having L members. For binary members of the cyclical sequence having values less than L/2 an amount (C/2−L) the most significant bit is forced to a logical “1” to create intermediate binary members. For members greater than or equal to an amount (C/2−L) is added to the binary to create intermediate binaries. The intermediate binaries are then transformed to a Gray code sequence having a non-standard sequence length of L.
