Half Adder, Half Subtracter, Full Adder, Full Subtracter

This is a half adder.

First attempt at Half Adder. A half adder is a logical circuit that adds to one bit binary numbers and results into a two digit output.

Half Adder for Students

Half Adder :-

The logic circuit which performs the addition of 2 bits is called Half- Adder. It is a kind of combinational circuit. It contains two binary inputs "augend" and "addend" and two binary outputs Sum and Carry.

Truth table:

Design of Half-Adder:

*formed using tools in simulator.

Full Adder :-

Full Adder is an arithmetic circuit which performs the arithmetic sum of 3-input bits. It consists of 3 inputs and 2 outputs. One additional input is the Carry bit (C) in which represents the carry from the previous significant position.

Truth table:

*C-Out represents carry output.

Design of Full-Adder using above formed Half-Adder:

*formed using tools in simulator.
