# Octal to Gray Code Converter

Octal to Gray Code Converter is used to convert a Octal number into Gray Code format. Use the Gray Code Converter tool to convert between any number base and gray code.

#### Gray to Octal

Convert Gray Code number to Octal

Background Information

### Octal

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

### Gray Code

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

### Conversion from Octal to Gray Code

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

1. Convert the input octal to binary
2. Take the first bit of the binary input and write it to the output
3. Repeat the following steps until you reach the end of the input
4. Take the second bit of the input and XOR it to the previous bit of the input
5. Write this result to the output. So, 0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1 and 1 + 1 = 0.

#### Example Octal to Gray Code Conversion

Let's say your Octal value is 255 and you want to convert it to it's Gray Code form.

1. Step 1: Convert the input octal to binary. So, 255 becomes 10101101
2. Step 2: Take the first bit of the binary input and write it to the output. Output is 1
3. 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: 11
• 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: 111
• 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: 1111
• 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: 11111
• 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: 111110
• Take the seventh bit of the input and XOR it to the previous bit. 1 + 0 = 1
• Write the result to the output. Output: 1111101
• 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: 11111011
4. Step 4: So, our final gray code result is: 11111011
