Half Adder and its Inputs
A half adder is a digital circuit that is used to add two binary digits together. It has two inputs, A and B, and two outputs, sum and carry. The sum output gives the result of adding the two inputs, while the carry output indicates if there is a carry from the least significant bit to the most significant bit.
Logic Gates in Half Adder
The half adder uses two logic gates, an XOR gate and an AND gate, to perform the addition. The XOR gate gives a 1 output when one and only one of its inputs is 1. The AND gate gives a 1 output only when both of its inputs are 1.
Sum of Half Adder
To find the sum of the two binary digits using a half adder, we use the XOR gate. The sum output is the result of the XOR gate.
Sum Output
The sum output is given by the Boolean expression A XOR B. This means that if A and B are different, the sum output will be 1. If A and B are the same, the sum output will be 0.
Conclusion
Therefore, the sum output of a half adder is given by A XOR B. This is because we want the sum output to be 1 only when one of the inputs is 1, but not both. The XOR gate is the logic gate that satisfies this condition.
