The 2-input “Exclusive-OR” gate is essentially a modulo-two adder since it offers the addition of two binary numbers and as a result are a lot of complicated in style than different basic forms of computer circuit.If associate degree XOR gate has over 2 inputs, then its behaviour depends on its implementation. The more than two input terminals XOR Gate also available. The Boolean expression for the Exclusive-NOR gate is given by Truth table for 2-input Ex-NOR gate The Boolean expression representing the 2 input XOR gate is written as \(Y=(A\bigoplus B)=\bar{A}.B +A.\bar{B}\), The Boolean expression for the three-input logic gate is given by \(Y=A\bigoplus B\bigoplus C=A\bar{BC}+\bar{A}B\bar{C}+\bar{AB}C+ABC\), In the above figure, three different logic gates are used to form an XOR, this is one of the main disadvantages. One of the easier ways to produce the XOR gate is to use only the combination of the NAND gate or NOR gate. Arduino Robot Kits Any expression following the AB’ + A’B form (two AND gates and an OR gate) may be replaced by a single Exclusive-OR gate.

XNOR Gate. You can also implement the exclusive OR gate with a combination of basic gates. Generally we follow IEEE (Institute of Electrical and Electronics Engineers) and IEC (International Electro-technical Commission) standards. The output signal is obtained by comparing different input bits through this gate. (B’ (A + B))’ =(A + (A + B)’). From this , it is clear that XOR gate produces a low logic that is logic ‘0’ , at its output , when both the inputs are same .When the two inputs are different it produces a logic high value i.e logic ‘1’ at its output. It can also be said as (A + B). The output of 2 input XOR gate is HIGH only when one of its inputs are high. The XOR circuit with 2 inputs is designed by using AND, OR and NOT gates is shown above. Quad Dual Input Exclusive OR Gate. 3. But XOR gate has its own significance. Best Function Generator Kits Exclusive OR Gate – EXOR Gate The EXOR gate is used extensively in digital data processing circuits and is known as Exclusive-OR-gate. Some of them are explained below. The logic symbol of an Exclusive-NOR gate is an XOR gate (Exclusive-OR gate) with the “inversion bubble” or the circle in front. XOR gate is used extensively in error detection circuits, computational logic comparators and arithmetic logic circuits. If both inputs are LOW or both are LOW, the output is LOW. This is a compound gate made up of AND, OR and NOT gates. Q = A  B  C = ABC + A’B’C + A’BC’ + AB’C’. For the two input EXOR gates, the output will be high when the set of input is either 01 or 10. As the basic AND gate implements the Boolean addition , while OR gate implements Boolean multiplication and NOT implements inversion function , there is no such Boolean function defined by the XNOR.This can be derived by basic gates (AND , OR ,NOT).Below shows the diagram of … X-OR logic gate is used in many applications. The output is “1” when there are an odd number of 1’s in the inputs. An exclusive gateway evaluates the state of the business process and, based on the condition, breaks the flow into one of the two or more mutually exclusive paths. Half Adder is the building block of the ALU (Arithmetic Logic Unit) which is used in every digital system. The IC diagram is shown below. If A, B are the inputs of XOR gate, its output is given as A.B ̅ +( A) ̅.B. […] The Exclusive-OR Function: The XOR Gate Chapter 7 - Boolean Algebra A suitable XOR gate can be used as a pseudo-random number generator. If both the inputs are same, then the output is LOW. Compare this image with the formula: X = AB + AB There are two remaining gates of the primary electronics logic gates: XOR, which stands for Exclusive OR, and XNOR, which stands for Exclusive NOR. Solar Light Kits Beginners We can design single bit adder, which will add two bits and produce a single bit output. Electronics Component Kits Beginners By applying Demorgan’s law, the output of Boolean expression is also written as (A + B). In an XOR gate, the output is HIGH if one, and only one, of the inputs is HIGH. For example, if we add two bits 1 and 1 in binary addition, we get the answer 10 and in decimal addition method we get 2. For XOR gates, we can have the HIGH input when odd numbers of inputs are at HIGH level. 2.
