| bin | gray | bin | gray | bin | gray | bin | gray |
|---|---|---|---|---|---|---|---|
| 0000 | 0000 | 0100 | 0110 | 1000 | 1100 | 1100 | 1010 |
| 0001 | 0001 | 0101 | 0111 | 1001 | 1101 | 1101 | 1011 |
| 0010 | 0011 | 0110 | 0101 | 1010 | 1111 | 1110 | 1001 |
| 0011 | 0010 | 0111 | 0100 | 1011 | 1110 | 1111 | 1000 |
Note - Binary to Gray conversion
The most significant bit (MSB) of the Gray code is the same as the MSB of the binary input. Each subsequent bit of the Gray code is obtained by XORing the current bit of the binary input with the previous bit.
