## How can we make XOR gate with OR or NOT gate?

If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is “must have one or the other but not both”….XOR gate.

Input | Output | |
---|---|---|

A | B | A XOR B |

0 | 0 | 0 |

0 | 1 | 1 |

1 | 0 | 1 |

## What does an XOR gate do?

An XOR gate (sometimes referred to by its extended name, Exclusive OR gate) is a digital logic gate with two or more inputs and one output that performs exclusive disjunction. If both of an XOR gate’s inputs are false, or if both of its inputs are true, then the output of the XOR gate is false.

## What is the truth table for XOR gate?

Truth Table: The output of an XOR gate is high (1) only when exactly one of its inputs is high (1). If both of an XOR gate’s inputs are low (0), or if both of its inputs are high (1), then the output of the XOR gate is low.

## What is the expression of ex OR gate?

The symbol used to describe the Boolean expression for an Exclusive-OR function is a plus sign, ( + ) within a circle ( Ο ). This exclusive-OR symbol also represents the mathematical “direct sum of sub-objects” expression, with the resulting symbol for an Exclusive-OR function being given as: ( ⊕ ).

## What is combination of XOR?

An XOR Gate is a combination of the following gates: two NOT Gates. two AND Gates. one OR Gate.

## How many and OR and XOR gates are required?

Explanation: There are three product terms. So, three AND gates of two inputs are required. As only two input OR gates are available, so two OR gates are required to get the logical sum of three product terms….Digital Circuits Questions and Answers – Logic Gates and Networks – 1.

INPUT | OUTPUT | |
---|---|---|

A | B | C |

0 | 0 | 1 |

0 | 1 | 0 |

1 | 0 | 0 |

## What is the difference between XOR and OR gate?

Another way to explain an XOR gate is as follows: The output is HIGH if the inputs are different; if the inputs are the same, the output is LOW. The XOR gate has a lesser-known cousin called the XNOR gate. An XNOR gate is an XOR gate whose output is inverted….Electronics Logic Gates: XOR and XNOR Gates.

Input A | Input B | Output |
---|---|---|

1 | 0 | 1 |

1 | 1 | 0 |

## HOW DO OR and XOR logic gates differ?

OR is true if at least one of the operands is true. XOR is true if exactly one of the operands is true.

## What is exclusively or gate?

An exclusive OR gate (XOR gate) is a digital logic gate that is implemented using transistors in order to act as an electronic switch used in implementing Boolean functions. It is built by combining standard logic gates such as the common NAND and NOR gates in order to produce the more complex function of this gate.

## What is the difference between OR gate AND exclusive OR gate?

xor is only true when either $x or $y is true, but not both (as the case for or ). xor means “exclusive or”. That is to say, it’s or, but with the single change that if both parameters to the operation are true, the answer is false.

## What is EX OR gate and ex NOR gate?

Hint: An EX-OR gate is a digital logic gate which gives a true output when the number of inputs is odd only. Whereas, EX-NOR gate is just an EX-OR gate followed by a NOT gate which gives a true output only when the number of inputs is even.

## Is XOR universal gate?

You can’t derive an OR (or AND, NOR, NAND) gate from only XOR (or XNOR) gates, because they are not universal gates. Here is an argument against XOR and XNOR as universal gates. An XOR gate is a parity generator. Cascading parity generators always produce parity generators.

## Which is the correct definition of an XOR gate?

What is an XOR Gate? An XOR gate (also known as an EOR, or EXOR gate) – pronounced as Exclusive OR gate – is a digital logic gate that gives a true (i.e. a HIGH or 1) output when the number of true inputs is odd.

## Can a circuit be constructed from an XNOR gate?

A circuit implementing an XOR function can be trivially constructed from an XNOR gate followed by a NOT gate. If we consider the expression, we can construct an XOR gate circuit directly using AND, OR and NOT gates. However, this approach requires five gates of three different kinds.

## Can a XOR gate be constructed using MOSFETs?

An XOR gate can be constructed using MOSFETs. Here is a diagram of a pass transistor logic implementation of an XOR gate. Note: The “Rss” resistor prevents shunting current directly from “A” and “B” to the output.

## How are XOR gates used in binary addition?

XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers. A half adder consists of an XOR gate and an AND gate.
