Q128 / 180 · NEET 2020 (Phase 2) · Physics

Which of the following gate is called universal gate?

  • A
    OR gate
  • B
    AND gate
  • Correct answer
    C
    NAND gate
  • D
    NOT gate

Solution

A universal gate is a logic gate which can implement any boolean function without the need to use any other type of logic gate. The NOR gate and NAND gate are universal gates. This means that you can create any logical boolean expression using only NOR gates or only NAND gates.

Hence, the correct answer is option: 'C'.
