Nand and Nor Gates

What is a type of logic gate which is the combination of AND and NOT gates and is

a commonly used logic gate.

• NOR gate

• AND gate

• NAND gate

• OF gate

Type of logic gate formed with the combination of the digital logic

OR gate and an inverter.

• NOR gate

• AND gate

• NAND gate

• OF gate

Which are the UNIVERSAL GATES?

• XOR Gate & NOT Gate

• AND Gate & OR Gate

• NAND Gate & NOR Gate

• All of the above

NAND Gate is called a universal logic element, because

• It is used by everybody

• Any logic function can be realised by NAND Gate alone

• Many digital computers use NAND Gate

• All the minimisation techniques are applicable to optimum NAND Gate realisation

The inputs of a NAND Gate are connected together. The resulting circuit is .............

• AND Gate

• OR Gate

• NOT Gate

• None of the above

What is the output of a NAND gate when both inputs are 1?

• 0

• 1

• Undefined

• Depends on the current

• NOR Gate

• NAND Gate

• XOR Gate

What is the output of a NOR gate when both inputs are 0?

• 0

• 1

• Undefined

• Depends on the current

Which gate is equivalent to an OR gate followed by a NOT gate?

• AND Gate
