The truth table tell us which values we expect on the output of the XOR gate for which values of the inputs A and B. The interconnection of gates to perform a variety of logical operation is called logic design. + A A

An alternative arrangement is of five NOR gates in a topology that emphasizes the construction of the function from When both inputs A and B are low then the output of the XOR Gate will be low. ¯

( | It may be noted that if both the inputs of the XOR gate are high, then the output is low (i.e., 0).

| Let's understand. By using these gates we can create any logic gate by combining them. In a two-input XOR Gate when only one input is high then the output will be high otherwise the output will be low.

a By using this gate, we can implement NOR and NAND gates. The symbol and truth table of an OR gate with two inputs is shown below. The basic logic gates are categorized into seven: AND, OR, XOR, NAND, NOR, XNOR and NOT.

If we consider the expression , noting from de Morgan's Law that a NAND gate is an inverted-input OR gate. This is all about the basic logic gates, which includes AND gate, OR gate, NAND gate, NOR gate, EX-OR gate and EX-NOR gate. =

{\displaystyle (A+B)\cdot ({\overline {A}}+{\overline {B}})} This article is about XOR in the sense of an electronic logic gate (e.g. (

of High input signal is odd. In order to have a better understanding of such a complex issue, we must have to acquaint ourselves with the term Boolean Logic, developed by George Boole.

B ≡ Example of XOR Gate ICs given here. It performs based on the operation of NOR gate. a

As IC technology advances, the desired physical volume for every individual gate decreases and digital devices of an equivalent or smaller size become capable of activity with more complicated operations at ever-increasing speeds.

This makes it practically useful as a parity generator or a modulo-2 adder. All logic gates obey their truth table. It performs based on the operation of OR gate. The NOR gate is a digital logic gate with n inputs and one output, that performs the operation of the OR gate followed by the NOT gate. Boolean expression and truth table: Y=A⊕B=A¯B+AB¯¯¯¯ B Resistor 5. Apart from the AND, OR, NOT, NAND, and NOR gate, there are two special gates, i.e., Ex-OR and Ex-NOR. ¯ This gate is a special type of gate used in different types of computational circuits.

Note: The "Rss" resistor prevents shunting current directly from "A" and "B" to the output. The Exclusive-OR gate is a digital logic gate with two inputs and one output. Electrical Engineering Interesting Questions and Answers, Electronics Engineering Interesting Questions and Answers. XOR from NAND logic, NAND to XOR conversion, equations, circuit, minimizatio Truth tables.

Pseudo-random number (PRN) generators, specifically Linear feedback shift registers, are defined in terms of the exclusive-or operation. ( For example, if we add 1 plus 1 in binary, we expect a two-bit answer, 10 (i.e. ¯ To get a clearer picture of what this operation does we can visualize it with the help of a Truth Table below. But, how these hardware and software perform such operations is a mysterious puzzle. It is most common to regard subsequent inputs as being applied through a cascade of binary exclusive-or operations: the first two signals are fed into an XOR gate, then the output of that gate is fed into a second XOR gate together with the third signal, and so on for any remaining signals. The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. ) If both inputs are false (0/LOW) or both are true, a false output results. An XOR gate circuit can be made from four NAND gates.

XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. (Note that the caret does not denote logical conjunction (AND) in these languages, despite the similarity of symbol.
