Published: 29.01.2021  An adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors adders are used in the arithmetic logic units or ALU. They are also used in other parts of the processor, where they are used to calculate addresses , table indices, increment and decrement operators and similar operations. Although adders can be constructed for many number representations , such as binary-coded decimal or excess-3 , the most common adders operate on binary numbers. In cases where two's complement or ones' complement is being used to represent negative numbers , it is trivial to modify an adder into an adder—subtractor. Other signed number representations require more logic around the basic adder. The half adder adds two single binary digits A and B. The half adder circuit has two inputs: A and B, which add two input digits and generates a carry and a sum. There will be no forwarding of carry addition because there is no logic gate to process that. Thus, this is called Half Adder circuit. Equation obtained by EX-OR gate is the sum of the binary digits. While the output obtained by AND gate is the carry obtained by addition. Attention reader! Writing code in comment?

An Adder is a device that can add two binary digits. It is a type of digital circuit that performs the operation of additions of two number. It is mainly designed for the addition of binary number, but they can be used in various other applications like binary code decimal, address decoding, table index calculation, etc. There are two types of Adder. One is Half Adder , and another one is known as Full Adder. The detailed explanation of the two types of adder is given below. Before you go through this article, make sure that you have gone through the previous article on Half Adder. Also Read- Full Subtractor. Watch this Video Lecture. Next Article- Half Subtractor.

An adder is a device that will add together two bits and give the result as the output. The bits being added together are called the "addends".
