This is because Gray codes are named after Frank Gray, who patented their use for shaft encoders in 1953. You can find a really Interesting Paper on this at www.faqs.org. One way to avoid this problem ...

Now, as we discussed in my Original Article, we can generate a 2^n binary-to-Gray converter using (n – 1) XOR gates; thus, our 4-bit binary-to-Gray converter will require only three XOR gates. The ...

It is simple to convert candidate_number to its binary representation, as follows:. candidate = 1 << (candidate_number - 1). Checking if a candidate is present in the set. As mentioned above, the set ...
