1. 4-bit binary code versus 4-bit Gray code. Gray codes are of use for a variety of applications, such as the ordering of the input variables on Karnaugh Maps (you can see examples of this in Fig 4 ...

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 ...

Grey coding ensures that just one bit changes at a time. The example he uses to show the importance of this is when binary code transitions from 7 (0b0111) to 8 (0b1000). Three digits have been ...
