How and gate can be realized using NAND?
NAND gate is actually a combination of two logic gates: AND gate followed by NOT gate. So its output is complement of the output of an AND gate. This gate can have minimum two inputs, output is always one. By using only NAND gates, we can realize all logic functions: AND, OR, NOT, X-OR, X-NOR, NOR.

How many 2-input NAND gates are required to implement the function?
Detailed Solution. The number of 2-input NAND gates required to implement a 2-input XOR gate is 4.
What will be the output of a 2-input NAND gate?
By De Morgan’s laws, a two-input NAND gate’s logic may be expressed as AB=A+B, making a NAND gate equivalent to inverters followed by an OR gate. The NAND gate is significant because any boolean function can be implemented by using a combination of NAND gates. This property is called functional completeness.
What is NAND gate why it is called universal gates?
An OR gate can be replaced by NAND gates as shown in the figure (The OR gate is replaced by a NAND gate with all its inputs complemented by NAND gate inverters). Thus, the NAND gate is a universal gate since it can implement the AND, OR and NOT functions.
Can you realize a 2 input NOR using 2 input NAND gates only?
NAND gate is actually a combination of two logic gates i.e. AND gate followed by NOT gate. This gate can have minimum two inputs, output is always one. By using only NAND gates, we can realize all logic functions: AND, OR, NOT, X-OR, X-NOR, NOR. So this gate is also called as universal gate.
How many NOR gates are required to make a NAND gate?
four NOR gates
NAND: It takes four NOR gates to create a NAND gate. The first three NOR gates are configured just as they are for an AND gate. Then a fourth NOR gate configured as a NOT gate inverts output from the third NOR gate.
What is the minimum number of two input NAND gates?
NAND and NOR gates are universal gates. By using of these gates we can realize any gate. T the minimum number of two-input NAND gates used to perform the function of 2-input OR gate are 3.
How many NAND gates are required to make a NOR gate?
Now, 4 gates are essential to form NAND gates. For Input: For input it is important to have 2 NOR gates. These should be single inputs for input.
