2 Bit Adder Logic Diagram. Introduction the adder is a digital circuit which forms the sum and carry of two or more numbers. It contains 2 inputs and 2 outputs sum and carry.
Truth table of 2 bit full adder. Half adder half adder is a combinational logic circuit. Serial binary adder functions bit by bit addition.
As discussed above there are total three inputs and two outputs of full adder.
000 0 001 1 010 1 011 10. 12 shows the sum logic circuit diagram. A and b be the two numbers each of two bits. Implement full adder using half adder.
