By How do you explain nor Gates?
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.
What is a NOR gate equivalent to?
As a NOR gate is equivalent to an OR gate leading to NOT gate, joining the inputs makes the output of the “OR” part of the NOR gate the same as the input, eliminating it from consideration and leaving only the NOT part.
Where do we use NOR gate?
NOR gate is used to construct the basic gates similar to AND gate. By combining NOT gate and OR gate, NOR gate can be constructed. The output of NOR gate is reversal of OR gate. Generally, NOR gate have 2 inputs, let’s say X and Y, and one output Z.
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.
What is NOR gate with diagram?
A NOR gate (“not OR gate”) is a logic gate that produces a high output (1) only if all its inputs are false, and low output (0) otherwise. Hence the NOR gate is the inverse of an OR gate, and its circuit is produced by connecting an OR gate to a NOT gate.
How many NOR gates are required for and gate?
three NOR gates
AND: You need three NOR gates to create an AND gate. The first two are configured as NOT gates, so they invert the inputs. Then the third NOR gate produces a HIGH output if both of the original inputs are HIGH. NAND: It takes four NOR gates to create a NAND gate.
How many NOR gates are required to make an AND gate?
What is the difference between OR gate and NOR gate?
The NOR gate is a combination OR gate followed by an inverter. Its output is “true” if both inputs are “false.” Otherwise, the output is “false.” The XNOR (exclusive-NOR) gate is a combination XOR gate followed by an inverter. Its output is “true” if the inputs are the same, and “false” if the inputs are different.
Why NOR gate is called universal gate explain?
2. One NOR input pin is connected to the input signal A while all other input pins are connected to logic 0. The output will be A’. Thus, the NOR gate is a universal gate since it can implement the AND, OR and NOT functions.
How do I make a NOR gate?
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.
