Half Adder Logic Circuit Diagram. In the above circuit diagram it is apparent that one and gate is used along with ex or gate. The above discussed logic of half adder can also be realized by the help of either nor or nand gate only.
Half adder circuit diagram a half adder consists of two inputs and produces two outputs. S a b cin a bc in abcin. S a b cin a bc in abcin.
Thus c out will be an or function of the half adder carry outputs.
We know the equations for s and cout from earlier calculations as. Half adder truth table. This is the simplest of all the other possible designs of half adder. The σ column is our familiar xor gate while the c out column is the and gate.
