Question:
For a half adder, the Sum and Carry outputs are respectively
For a half adder, the Sum and Carry outputs are respectively
Show Hint
Half adder outputs are \(S=A\oplus B\) and \(C=AB\).

- \(A+B,\ AB\)
- \(A\oplus B,\ AB\)
- \(AB,\ A+B\)
- \(A\oplus B,\ A+B\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A half adder adds two binary bits and produces two outputs: Sum and Carry.
Step 1: The Sum output is \(1\) when inputs are different. This is XOR operation: \[ S=A\oplus B \]
Step 2: The Carry output is \(1\) only when both inputs are \(1\). This is AND operation: \[ C=AB \] Therefore: \[ \boxed{A\oplus B,\ AB} \]
Step 1: The Sum output is \(1\) when inputs are different. This is XOR operation: \[ S=A\oplus B \]
Step 2: The Carry output is \(1\) only when both inputs are \(1\). This is AND operation: \[ C=AB \] Therefore: \[ \boxed{A\oplus B,\ AB} \]
