Firstly we discuss about Adder Definition of adder: Adders are the combinational logic circuits which are used for adding two or three binary bits. Types of Adder: Half adder Full adder powered by jpwebdevelopers
HALF ADDER Definition of Half adder: Half adder add two binary digits and produces two binary outputs called sum and carry. It generates sum(s) and carry(c) as output. Block Diagram: Half adder powered by jpwebdevelopers

Full Adder Full adder has three input bits A,B and additional carry-in(in) It is used to add three bits and generate two output sum(s),carry(c) Block diagram: sum Inputs outputs carry Full adder powered by jpwebdevelopers
