Question

What is the output of a NAND gate for the inputs A = 1, B = 1?

• A. 1
• B. 0
• C. 2
• D. Undefined

Hint:

Remember that NAND = NOT(AND). If both inputs are 1, the output is always 0.

Answer 1

The Correct Option is B

The NAND gate output is the negation of the AND gate output. For inputs A = 1 and B = 1, the AND gate gives 1, and negating it gives 0.
