A 'half-adder' in digital circuits is a combinational circuit that can add:
a)
Two 2-bit binary numbers.b)
Two single binary digits and produce a sum and a carry.c)
Three single binary digits (including a carry-in).d)
Two binary numbers of any length.Explanation
A half-adder is the simplest form of digital adder. It takes two inputs (A and B) and produces two outputs: Sum (S) and Carry (C). It is typically built using one XOR gate for the Sum (A ⊕ B) and one AND gate for the Carry (A ⋅ B).Related questions
