Excess-3 code is known as_________________?
Correct answer: C. Self-complementing code
- A. Weighted code
- B. Cyclic redundancy code
- C. Self-complementing code
- D. Algebraic code
Explanation
Excess-3 is formed by adding 3 to each decimal digit and is self-complementing: complementing its four bits gives the Excess-3 representation of the 9's complement digit. It is therefore not a weighted code.
