The excess-3 binary code is a sequential code, so we can use it to perform arithmetic operations. Also, it is a self-complementing code, therefore the subtraction operation by the complement method is simpler than that in the 8421 BCD code....
Excess-3 code is a BCD code. It is a self-complementing code, but not a weighted code. In earlier articles, we have seen decimal to binary conversion, decimal to 8421 BCD conversion and vice versa. In this article, we will learn about Excess-3 code and i
