Background

Decimal

Decimal is the numeric system most used by us humans. It consists of the Hindu-Arabic numerals, a set of 10 digits from 0 to 9.

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 Decimal to Gray Code

A Decimal can be converted to Gray Code using these steps:-

  1. Convert the input decimal 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 Decimal to Gray Code Conversion

Let's say your Decimal value is 173, and you want to convert it to its gray code form.

  1. Step 1: Convert the input decimal to binary. So, 173 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
