# How AND gate can be formed by using two NOR gates?

## How AND gate can be formed by using two NOR gates?

NAND and NOR gates are called “Universal” gates as any kind of logic gate can be obtained by using combinations of these. To get an AND gate we can use two NAND gates. Now give Q as input to second NAND gate ( join the inputs together, i.e. Q will be the input to both the terminals of second NAND gate).

How do you convert NOR to NAND?

To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.

### How do you use NOR gate as AND gate?

An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined….AND.

Input A Input B Output Q
0 1 0
1 0 0
1 1 1

How can you obtain OR AND AND gate from NOR gate?

To obtain an AND gate from NOR gates, we feed input A and B into two separate NOR gates with joined input to obtain a NOT (A) and a NOT (B) separately. Then this two different outputs are fed into either input (i.e. NOT (A) to one Input terminal and NOT (B) to another terminal). The result will be an AND gate.

#### How do you make a NOR gate with OR gate?

How do you make an OR gate with AND AND NOT gates?

## How no gate is obtained from NOR gate?

HOW AND gate is Realised practice?

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.

### Why is NAND and NOR universal gates?

Answer: The NAND & NOR gates are called universal gates because they perform all the logical operations of basis gates like AND, OR, NOT. Answer: NOR AS AND An AND gate gives a 1 output when both inputs are 1; a NOR gate gives a 1 output only when both inputs are 0.

What is NOR gate logic?

Definition – What does NOR Gate mean? A NOR gate is a type of logic gate that works on the principle of “neither this nor that.” This type of digital logic gate produces a high output only if two binary results are satisfied by a zero or low input. Techopedia explains NOR Gate

#### What is logic NOR gate?

– Logic Gates. A logic gate is a simple switching circuit that determines whether an input pulse can pass through to the output in digital circuits. – Boolean Algebra. – Types of Logic Gates. – Basic Logic Gates. – Universal Logic Gates. – Other Logic Gates. – Uses of Logic Gates. – Sample Questions.

What is NOR gate circuit?

NOR Gate – Symbol, Truth table & Circuit. A NOR gate is a digital logic gate that implements logical NOR operation. It is a combination of an OR gate and NOT gate. If we connect the output of OR gate to the input of a NOT gate, the gate so obtained is known as NOR gate. This gate is also called as Negated OR gate.
