21 from Decimal to Gray Code

Converting a decimal number to Gray code involves converting the decimal number to binary first, then performing a binary-to-Gray-code conversion. Here's a step-by-step guide with an example for decimal number 21:

Step 1: Convert Decimal to Binary

Convert the decimal number 21 to binary:

21₁₀ = 10101₂

Step-by-step converting 21 from decimal to binary

Step 1: Write Down the First Bit of the Gray Code

Write down the first bit of the Gray code as the same as the first bit of the binary number.

FIRST BIT OF GRAY CODE: 1

Step 2: perform the XOR operation of the first and the second bits of the binary number

The 1st bit is 1, and the 2nd bit is 0. Both the bits are different, so the second bit of the Gray code is 1.

Step 3: perform the XOR operation of the second and the third bits of the binary number

The 2nd bit is 0, and the 3rd bit is 1. Both the bits are different, so the third bit of the Gray code is 1.

Step 4: perform the XOR operation of the third and the fourth bits of the binary number

The 3rd bit is 1, and the 4th bit is 0. Both the bits are different, so the fourth bit of the Gray code is 1.

Step 5: perform the XOR operation of the fourth and the fifth bits of the binary number

The 4th bit is 0, and the 5th bit is 1. Both the bits are different, so the fifth bit of the Gray code is 1.

So, the Gray code for the decimal number21 is 11111.
