What is Full Adder?

The Full Adders are a type of digital logic circuit that is computed to perform addition. They can be thought of as the simplest possible form of the digital circuit since they perform a single function and have no internal logic. Full adders consist of sequences of the basic logic gates used in digital circuits, such as two EX-OR gates, two AND gates, and one OR gate. Full adders are the most basic building blocks in are the design of more complex digital circuits, such as processors.

Logical Expression:

SUM = (A XOR B) XOR Cin = (A ⊕ B) ⊕ Cin
CARRY-OUT = A AND B OR Cin(A XOR B) = A.B + Cin(A ⊕ B)
