Octal to Gray Code Converter is used to convert a Octal number into Gray Code format

A Octal can be converted to Gray Code in three steps:-

- Convert the input octal to binary
- Take the first bit of the binary input and write it to the output
- Repeat the following steps until you reach the end of the input
- Take the second bit of the input and XOR it to the previous bit of the input
- Write this result to the output. So,
`0 + 0 = 0`

,`0 + 1 = 1`

,`1 + 0 = 1`

and`1 + 1 = 0`

.

Let's say your Octal value is `255`

and you want to convert it to it's Gray Code form.

**Step 1:**Convert the input octal to binary. So,`255`

becomes`10101101`

**Step 2:**Take the first bit of the binary input and write it to the output. Output is**1****Step 3:**Repeat the steps below until you reach the end of the input- Take the second bit of the input and XOR it to the previous bit of the input.
`1 + 0 = 1`

- Write the result to the output. Output:
`1`

**1** - Take the third bit of the input and XOR it to the previous bit of the input.
`0 + 1 = 1`

- Write the result to the output. Output:
`11`

**1** - Take the fourth bit of the input and XOR it to the previous bit of the input.
`1 + 0 = 1`

- Write the result to the output. Output:
`111`

**1** - Take the fifth bit of the input and XOR it to the previous bit of the input.
`0 + 1 = 1`

- Write the result to the output. Output:
`1111`

**1** - Take the sixth bit of the input and XOR it to the previous bit of the input.
`1 + 1 = 0`

- Write the result to the output. Output:
`11111`

**0** - Take the seventh bit of the input and XOR it to the previous bit.
`1 + 0 = 1`

- Write the result to the output. Output:
`111110`

**1** - Take the eighth (last) bit of the input and XOR it to the previous bit.
`0 + 1 = 1`

- Write the result to the output. Output:
`1111101`

**1**

- Take the second bit of the input and XOR it to the previous bit of the input.
**Step 4:**So, our final gray code result is:`11111011`

Octal number system is composed of digits from 0 to 7. It has a base of 8 hence the name Octal.

Gray Code is an ordering of binary numeral system used for error correction in digital terrestrial television and some cable TV systems.

3 | 3 | 0011 | 0010 |

4 | 4 | 0100 | 0110 |

5 | 5 | 0101 | 0111 |

6 | 6 | 0110 | 0101 |

7 | 7 | 0111 | 0100 |

8 | 8 | 1000 | 1100 |

9 | 9 | 1001 | 1101 |

10 | a | 1010 | 1111 |

11 | b | 1011 | 1110 |

12 | c | 1100 | 1010 |

13 | d | 1101 | 1011 |

14 | e | 1110 | 1001 |
