What are the advantages of NOR gate?
When using a NOR Gate, using an Invertor is no longer necessary in combination with an OR Gate. It will give the same outcome, however, the NOR Gate gives the advantage that it needs little space, less material and is less complicated. At least one input must be active to stop the output power.
Where is ex-NOR gate used?
Ex-NOR gates are used mainly in electronic circuits that perform arithmetic operations and data checking such as Adders, Subtractors or Parity Checkers, etc.
What are the applications of NAND and NOR gates?
NAND Gate Applications. Logic NAND gate has many applications like Burglar alarm, freezer buzzer etc.
What are the five uses of logic gate?
Logic gates are used as building blocks of digital electronic hardware.
What are the advantages of NAND and NOR gates?
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. In fact, an AND gate is typically implemented as a NAND gate followed by an inverter not the other way around!!
Which is better NAND or NOR?
NAND has cascaded NMOS in pull down and parallel PMOS in pull up network . So during pull up for nor gate we have cascaded pmos gates which slows the operation . Stacking of PMOS is not recommended . So nand is preferred over nor gate .
What is NOR gate Class 12th?
Exclusive-NOR gate or XNOR gate is formed by combining the Exclusive-OR gate (XOR gate) and the NOT gate. On analysing the XNOR truth table, we understand that the output is similar to the standard NOR gate except that the output of the XNOR gate is high when both inputs are high.
What is difference between ex or and ex-NOR gate?
Hint: An EX-OR gate is a digital logic gate which gives a true output when the number of inputs is odd only. Whereas, EX-NOR gate is just an EX-OR gate followed by a NOT gate which gives a true output only when the number of inputs is even.
Which is better NOR or NAND?
What is meant by 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.
Is NOR a universal gate?
NAND logic — Like NOR gates, NAND gates are also universal gates.
Why NOR gate is known as universal gate?
∴ NAND and NOR gates are called universal gates because they can be combined to produce any of the other gates like OR, AND, and NOT gates.
Which is better NAND OR NOR?
Which logic gate is fastest?
Emitter-coupled logic (ECL)
Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as the fastest logic available.
Which IC is used for NOR gate?
74LS02 is a LOGIC GATE IC and member of 74XXYY IC series which are logic gates. There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE….74LS02 Pin configuration.
| Pin Number | Description |
|---|---|
| NORGATE 1 | |
| 2 | 1A-INPUT1 of GATE 1 |
| 3 | 1B-INPUT2 of GATE 1 |
| 1 | 1Y-OUTPUT of GATE1 |
What is the example of NOR gate?
A NOR gate or a NOT OR gate is a logic gate which gives a positive output only when both inputs are negative….XNOR.
| Desired XNOR Gate | NOR Construction |
|---|---|
| Q = A XNOR B | = [ A NOR ( A NOR B ) ] NOR [ B NOR ( A NOR B ) ] |
| Truth Table Input A Input B Output Q 0 0 1 0 1 0 1 0 0 1 1 1 |
How a NOR gate can be used to obtain and operation?
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 is NOR gate used in real life?
Logic NOR gate can be used to construct EX-OR gates and some other real time applications. One of its real time applications is ‘Mixer tank’. It is explained below. If you observe the below diagram, we use a 3-input NOR gate to control the flow of ingredients of a mixer tank.
Why are NAND and NOR gates more popular?
NAND and NOR gates are more popular as these are less expensive and easier to design. Also other functions NOT AND OR can easily be implemented using NAND/NOR gates. Thus NAND NOR gates are also referred to as Universal Gates.
What is the logic of NOR gate?
NOR logic. A NOR gate is a logic gate which gives a positive output only when both inputs are negative. Like NAND gates, NOR gates are so-called “universal gates” that can be combined to form any other kind of logic gate. For example, the first embedded system, Apollo Guidance Computer, was built exclusively from NOR gates,…
What is an EXNOR logic gate?
An EXNOR logic gate is the opposite of the XOR gate. We can extend the functionality of the gates we have seen so far by just attaching an inverter to them. This will allow us to have more options of creating complex logic using essentially the same gates that we have seen so far, albeit with an inverter attached at their outputs.
Why NAND and NOR logic gates are called universal gates?
NAND and NOR logic gates are known as universal gates because they can implement any boolean logic without needing any other gate. They can be used to design any logic gate too. Moreover, they are widely used in ICs because they are easier and economical to fabricate. How to design all gates using NAND and NOR logic gates?
What are some real life examples of logic gates?
What are the real life examples of logic gates? Consider a house with two power supply-the major power supply from electricity board or power station and the secondary supply is an Inverter/Generator. Now assume, if there is no power from electricity board/power station, but Inverter is charged, so you can operate your bulb.
