Question

Two inputs A and B of NAND gate have 0 output, if:

• A. A is 0
• B. B is 0
• C. Both are zero
• D. Both are 1

Hint:

The NAND gate is the inverse of the AND gate, giving a 0 output only when both inputs are 1.

Answer 1

The Correct Option is D

A NAND gate gives an output of 0 only when both inputs are 1. In all other cases, the output is 1.
