## What does an AND gate do?

The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – AND gate behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1).

### WHAT IS AND gate example?

The logic AND Function For example, A & B = B & A. In Boolean algebra the Logic AND Function follows the Commutative Law which allows a change in position of either variable. Thus a 2-input (A B) AND Gate has an output term represented by the Boolean expression A. B or just AB.

#### WHAT IS AND gate in physics?

AND gate: The AND gate is defined as a digital logical gate in which the low input will give you low output whereas the high input will give you high output. Therefore, the input can be two or more than one signal whereas the output will be two signals only.

HOW AND gate is Realised?

To build an inverter from NAND, simply connect the two inputs of the NAND together and use this junction as input of the inverter. Therefore an AND gate can be realized simply as a NAND followed by another NAND with 2 inputs tied together.

IS AND gate multiplication?

The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.

## What is meant by a logic gate?

A logic gate is a device performing a Boolean logic operation on one or more binary inputs and then outputs a single binary output. Computers perform more than simple Boolean logic operations on input data, and they typically output more than a single binary digit.

### What is combination of AND AND NOT gate?

The combination of an AND gate and a NOT gate is called a NAND gate, as shown in the diagram.

#### IS AND gate an addition?

OR gate and its timing diagram Writing the OR logic function as an algebraic equation, OR is boolean addition so that a + b denotes a OR b.

What is logic gate and its type?

A logic gate is a basic building block of a digital circuit that has two inputs and one output. The basic logic gates are categorized into seven: AND, OR, XOR, NAND, NOR, XNOR, and NOT. These logic gates with their logic gate symbols and truth tables are explained below.
