The simplest digital circuit used to implement the binary addition is the half adder which has two inputs and two outputs. Just as in the decimal number systems the weight of the digit depends on the position of the binary digits in the binary number systems as well. Only two digits ‘0’ and ‘1’ are available in the binary number system where the 1 is the largest and 0 is the smallest digit respectively. In the binary addition as the name suggest binary numbers are added to yield the sum of the binary numbers. Binary addition is exactly similar to the denary addition and also follows the same rule: the only difference is the number system on which each addition operates. Half Adder is the digital logic circuit that is used to implement the binary addition. In addition to arithmetic operations other important functions are also performed by the digital systems. Introduction to Half AdderĪrithmetic operations performed by the digital circuits include addition, subtraction, multiplication and division. One of the most important operations performed by the digital systems is the Arithmetic operations. As the digital systems were also very effective and reliable further applications of digital circuits came into the field. For instance digital circuits are used for digital signal processing functions such as filtering which were prior to the digital circuits were done using the analog circuits. Since the advent of the digital technology in electronics a variety of operations that were formerly performed by the analog circuits were continued to be implemented digitally in digital circuits.
