Full Adder Full adder is a circuit which is used to calculate three digits in the form of sum and carry. It will calculate the sum of three bits along with the carry as mentioned below. Full adder can be form by using two half adder circuit to get sum and carry. The main difference between a half-adder and a full-adder is that the full-adder has three inputs and two outputs. The first two inputs are A and B and the third input is an input carry designated as CIN. The Full-Adder is the actual block that we will use to create the arithmetic circuits. 1.We add two half adder circuits with an extra addition of OR gate and get a complete full adder circuit. 2. Twohalf adder circuits added together with a OR gate. ...
