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 ...

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).

So, that answers the first portion of my ponderable, but what about the second part, in which I said: “If it is possible to achieve a ternary Gray code, can we map binary values onto the ternary ...
