What is Excess-3 Code?
Excess-3 Code is a non-weighted binary code used to represent decimal digits. It is created by adding 3 to each decimal digit and then converting the result into a 4-bit binary number.
Decimal digit: 5 Add 3: 5 + 3 = 8 Convert 8 to binary: 1000 Excess-3 Code: 1000
How to Convert Decimal to Excess-3 Code
Follow these steps:
- Separate each decimal digit.
- Add 3 to every digit.
- Convert each result into a 4-bit binary number.
- Combine all 4-bit groups to get the Excess-3 code.
Example: Decimal: 25 Digit 2: 2 + 3 = 5 5 = 0101 Digit 5: 5 + 3 = 8 8 = 1000 Excess-3: 0101 1000

Frequently Asked Questions
Excess-3 Code is a binary coding system where each decimal digit is increased by 3 before conversion into binary.
Excess-3 does not assign fixed positional weights to binary bits like standard weighted codes.
Decimal 9 + 3 = 12. Binary representation of 12 is 1100, so the Excess-3 code of 9 is 1100.
Excess-3 is mainly used in digital electronics, arithmetic circuits, and decimal processing applications.
