Which of the following expressions is not True about NAND gates in Boolean Algebra?

  1. A.

    It is a Universal Gate

  2. B.

    It is NOT gate of AND gate

  3. C.

    For variables U and V, NAND is represented as (U · V)'

  4. D.

    Every Boolean Expression cannot be represented with the help of NAND gate only

Attempted by 270 students.

Show answer & explanation

Correct answer: D

NAND gates are universal gates, meaning any Boolean expression can be implemented using only NAND gates. Consequently, the statement suggesting that Boolean expressions cannot be represented using only NAND gates is incorrect.
