## What is the truth table for NAND gate?

2-input Logic NAND Gate

Symbol | Truth Table | |
---|---|---|

2-input NAND Gate | 0 | 1 |

1 | 0 | |

1 | 1 | |

Boolean Expression Q = A.B | Read as A AND B gives NOT Q |

**What is the symbol of NAND gate?**

The Boolean equation of NAND gate is `Y=bar(A*B)` and it is read as “Y is equal to NOT A and B”. NAND gates are also called universal gates since by using the gates you can realise other basic gates like OR, AND and NOT.

**What is a NAND gate write its logic symbol AND truth table?**

The logic gate is an electronic circuit having one or more inputs and a single output. These gates are constructed using diodes and transistors. Boolean algebra is the mathematical expression that explains the output of logic gates….Symbol and truth table of NAND gate.

A | B | Y |
---|---|---|

0 | 0 | 1 |

0 | 1 | 1 |

1 | 0 | 1 |

1 | 1 | 0 |

### What is the symbol of XNOR gate?

⊙

The logical XNOR operation is represented by ⊙. That is a dot surrounded by a circle. The expression of XNOR operation between variables A and B is represented as A ⊙ B.

**Can NAND gate have one input?**

A NAND gate is a two-input and single output device. The number of inputs can be two or more according to the need. A NAND gate means, it is a combinational logic circuit and a NAND gate is formed by combining an AND gate followed by a NOT gate. If any of the one input is 0 then the output will be 1.

**What is XNOR gate symbol AND truth table?**

An XNOR gate is also called exclusive NOR gate or EXNOR gate. In a two-input XNOR gate, the output is high (logic 1 or true) when two inputs are the same. In Boolean expression, the term XNOR is represented by the symbol (⊙) and the Boolean expression is represented as Y = A ⊙ B. It is read as “A XNOR B”.

## What is logic gate Class 12?

The logic gates are the basic building blocks of digital electronics. We can say logic gate is a digital circuit which follows a logical relationship between the input and output. Some of the basic types of logical gate are – NOT, OR, AND, NOR and NAND. Every gate has a single or multiple input and output.

**What is NAND gate with examples?**

In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
