What does Gray code actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

And now you have your 10-bit Gray-code using consecutive addresses of 0000-to-1001 (0 to 9 in decimal). In this case, the sequence followed by this Gray code counter implementation is: 4, 6, 2, 0, 8, ...

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).

1. Binary code versus 4-bit Gray code. Observe that when we reach the final (maximum) Gray code value of 1000, the next “count” will return us to our initial value of 0000, which means that – as we ...

Take three filaments with the air-gap-pipe sensors spaced to form a Gray code, and he could digitally read the location. He appears to be developing this discovery into a product.
