Full Adder:-
- Full adder is a combinational logic circuit which can add three bits and produces sum and carry as output. Full adder performs binary addition on input A, input B and carry input Cin and produces output sum S and output carry Cout. The block diagram and truth table of full adder is given below.
| Inputs | Outputs | |||
|---|---|---|---|---|
| A | B | Cin | Cout | Sum |
| 0 | 0 | 0 | 0 | 0 |
| 0 | 0 | 1 | 0 | 1 |
| 0 | 1 | 0 | 0 | 1 |
| 0 | 1 | 1 | 1 | 0 |
| 1 | 0 | 0 | 0 | 1 |
| 1 | 0 | 1 | 1 | 0 |
| 1 | 1 | 0 | 1 | 0 |
| 1 | 1 | 1 | 1 | 1 |
