XOR gate - for calculating binary addition Half adder circuit consist of 2 logic gates namely : If A and B are the input bits, then sum bit (S) is the X-OR of A and B and the carry bit (C) will be the AND of A and B. Hence the circuit is known as a half-adder. Since any addition where a carry is present isn’t complete without adding the carry, the operation is not complete. The truth table of the half adder is shown below. Why is it called a half adder The half adder circuit adds two single bits and ignores any carry if generated. The half adder is the logic circuit that adds the two bits and generates the sum bit (S) and carry bit (C) as an output. Half adder is a combinational arithmetic circuit that adds two numbers and produces a sum bit (S) and carry bit (C) as the output. In this article, the logic circuit, the truth table, and the working of half adder and full adder are explained.
