Question
A half adder adds two bits to produce a sum of
Solution
A half adder adds two bits to produce a sum and a carry. Specifically, it produces two outputs:
-
Sum (S): This is the XOR (exclusive OR) of the two bits being added. It represents the sum of the two bits, ignoring any carry that might result.
-
Carry (C): This is the AND of the two bits being added. It represents whether a carry is generated by the addition of the two bits.
So, if the two bits being added are A and B, the outputs of the half adder would be:
S = A XOR B C = A AND B
For example, if A = 0 and B = 1, the sum S would be 1 (since 0 XOR 1 = 1) and the carry C would be 0 (since 0 AND 1 = 0).
