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

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 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.

Half Adder

In the preceding section, we discussed how two binary bits can be added and the addition of two binary bits with a carry. In practical situations it is required to add two data each containing more than one bit. Two binary numbers each of *n* bits can be added by means of a full adder circuit. Consider the example that two 4-bit binary numbers B _{4}B _{3}B _{2}B _{1} and A _{4}A _{3}A _{2}A _{1} are to be added with a carry input C _{1}. This can be done by cascading four full adder circuits as shown in Figure 5.48. The least significant bits A _{1}, B _{1}, and C _{1} are added to the produce sum output S _{1} and carry output C _{2}. Carry output C _{2} is then added to the next significant bits A _{2} and B _{2} producing sum output S _{2} and carry output C _{3}. C _{3} is then added to A _{3} and B _{3} and so on. Thus finally producing the four-bit sum output S _{4}S _{3}S _{2}S _{1} and final carry output Cout. Such type of four-bit binary adder is commercially available in an IC package.
