## How can you make not gate by using NOR gate and how?

NOT: Creating a NOT gate from a NOR gate is the same as creating a NOT gate from a NAND gate: You simply tie the two inputs of the NOR gate together. If both inputs are LOW, the NOR gate will output a HIGH. Otherwise, the output is LOW. OR: You need two NOR gates to create an OR gate.

## Is a NOR gate An AND gate?

A NAND gate is equivalent to an inverted-input OR gate. An AND gate is equivalent to an inverted-input NOR gate. A NOR gate is equivalent to an inverted-input AND gate.

## How do you make an OR gate?

In Boolean Algebra the OR function is the equivalent of addition so its output state represents the addition of its inputs. In Boolean Algebra the OR function is represented by a “plus” sign (+) so for a two input OR gate the Boolean equation is given as: Q = A+B, that is Q equals either A OR B.

## How many NOR gates are required to make an OR gate?

An XNOR gate is made by connecting four NOR gates as shown below. This construction entails a propagation delay three times that of a single NOR gate. , noting from de Morgan’s Law that a NOR gate is an inverted-input AND gate. This construction uses five gates instead of four.

## How many NOR gate is required to implement a AND gate?

XNOR. An XNOR gate is made by connecting four NOR gates as shown below. This construction entails a propagation delay three times that of a single NOR gate.

## How many NAND gates are required for NOT gate?

Only one NAND gate is required to make a NOT gate. If one input of a NAND gate is made permanently high, we get a NOT gate [see figure (a)]. Alternatively, if both the inputs of a NAND gate are tied together, we get a NOT gate.

## What is the use of NOR gate?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

## How to create an AND gate out of NOR gates?

“How can you create an AND gate out of NOR gates?” With the help of De Morgan’s laws – Wikipedia. The output of a 2-input OR gate is true, if either input A OR input B is true. In other words, the output is false, if input A is false AND input B is false.

## When is the NOR gate reverse of the OR gate?

As the NOR gate is reverse of OR gate when both inputs of NOR gate are 1, the output will be 0 and when both inputs of two inputs NOR gate 0, the output will be 1. Now if we short circuit both inputs of a NOR gate, then we will get, Where, X is either 0 or 1. So when X = 1, the output of the above gate is 1.

## Which is the output of the NOR gate?

The output of the NOR gate is always opposite of the input , which means that if we give logic 1 at the input of the gate then the output will be logic 0 and vice versa. The number of stages that can be obtained can be calculated by 2 n (where n is the number of input) .

## How to connect NAND logic gates to NOR gates?

1 NOT using NOR: It’s simple. 2 OR using NOR: Connect a NOT using NOR at the output of the NOR to invert it and get OR logic. 3 AND using NOR: Connect two NOT using NORs at the inputs of a NOR to get AND logic. 4 NAND using NOR: Just connect another NOT using NOR to the output of an AND using NOR. 5 EXNOR using NOR: This one’s a bit tricky.
