A half-adder is also known as :
Correct Answer: D
Question 7 Explanation:
→ The half adder adds two single binary digits A and B. It has two outputs, sum (S) and carry (C). The carry signal represents an overflow into the next digit of a multi-digit addition. The value
of the sum is 2C + S. The simplest half-adder design incorporates an XOR gate for S and an AND gate for C. The Boolean logic for the sum (in this case S) will be A′B + AB′ whereas for the carry (C) will be AB.
