What are the types of logic gates and truth tables?

The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. The truth table is used to show the logic gate function. All the logic gates have two inputs except the NOT gate, which has only one input.

Which logic gate is represented by the truth table?

The given logic gate represents NAND gate because the results are the complement of the AND gate .

What is basic logic gate?

A Logic gate is a kind of the basic building block of a digital circuit having two inputs and one output. The input and output relationship is based on a certain logic. These gates are implemented using electronic switches such as diodes, transistors.

How many types of basic gate are there?

The basic logic gates are categorized into seven types as AND, OR, XOR, NAND, NOR, XNOR, and NOT. These are the important digital devices, mainly based on the Boolean function. Logic gates are used to carry out the logical operations on single or multiple binary inputs and result in one binary output.

What is universal logic gate?

A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.

What is not logic gate?

In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. In mathematical logic it is equivalent to the logical negation operator (¬). The truth table is shown on the right.

What are the three types of logic gates?

For AND Gate – If both the inputs are high then the output is also high

For OR Gate – If a minimum of one input is high then the output is High

For XOR Gate – If the minimum one input is high then only the output is high

NAND Gate – If the minimum one input is low then the output is high

NOR Gate – If both the inputs are low then the output is high.

What are the basic logic gates?

The logic of this gate is that the output would be 1 when at least one of the inputs is 1.

If there are two inputs A and B,then the OR gate’s output will be given by the following mathematical operation: Y = A+B

The symbol and truth table for an OR gate can be given as:

What are the real life examples of logic gates?

Types of logic gates

The OR Gate. The OR gate has two inputs marked as A and B and output as C.

Diode OR Gate. When both A and B are at logic 0 i.e.connected to ground,both the diodes will be reverse baised at the out put will be at zero.

OR gate truth table

AND Gate.

Diode AND Gate.

AND gate truth table

NOT Gate.

What are the three ways to depict any logic gate?

– AND Gate: very similar to arithmetic multiplication. – OR Gate: very similar to arithmetic addition. – NOT Gate: invert the input ,that is if its 0 then output is 1 and if its 1 output is 0. – NAND Gate : NotAND :get the output as AND gate then apply a NOT expression.
