Question
If A and B are the inputs of a half adder, the sum is given by __________
a. A AND B
b. A OR B
c. A EX-NOR B
d. A XOR B
Solution
The sum in a half adder with inputs A and B is given by d. A XOR B.
Here's why:
A half adder is a type of adder, an electronic circuit that performs the addition of numbers. In a half adder, the sum is the result of the exclusive OR (XOR) of the inputs A and B.
The XOR operation gives a true (or '1') result if the number of true inputs is odd. For a half adder, this means that the sum is '1' if A is '1' and B is '0', or if A is '0' and B is '1'. If both A and B are '0' or both are '1', the sum is '0'.
So, the correct answer is d. A XOR B.
