Choose the correct answer:
- A.
two input two output
(Correct Answer) - B.
one input two output
- C.
two input one output
- D.
one input one output
two input two output
Explanation
Solution:
A Half Adder is a basic digital circuit that performs the addition of two single-bit binary numbers.
-
Inputs: It takes 2 binary inputs (usually denoted as A and B).
-
Outputs: It produces 2 binary outputs:
-
Sum (S): Represented by the XOR gate operation →S=A⊕B.
-
Carry (C): Represented by the AND gate operation →C=A⋅B.
-
Because it handles two input bits and generates both a sum and a carry bit, it is characterized as having two inputs and two outputs.
Correct Option: (a) two input two output
