What is a half-adder? Explain a half-adder with the help of truth-table and logic diagram.

Ans.
Half Adder: It is a logic circuit for the addition of two 1-bit numbers is termed  to as an half-adder. The process of addition is exemplified in truth table demonstrated in Table. There A and B are the two inputs and also S (SUM) and C (CARRY) are two outputs.

Truth Table for Half Adder

By the truth table, we get the logical expressions for S and C outputs that is
S = A B+A B
C = AB
