Editor's note: A few weeks ago, Programmable Logic DesignLine published an article on Gray code by an associate professor at the University of Arizona that directly addressed one of a series of Gray code questions we put forth in 2007.
Recently the author got back in touch with us and generously gave us permission to publish another article he wrote on Gray code. This work develops a systematic method of computing Gray code sequences using only the binary representations of numbers from 0 through N-1.
Thanks Srini for sharing your work.
