What does the small bubble on the NAND gate's logic symbol means with respect to the output?

  1. A.

    The output is inverted

  2. B.

    The output is enabled

  3. C.

    The output is disabled

  4. D.

Show answer & explanation

Correct answer: A

In digital logic diagrams, a small circle or "bubble" represents an inversion operation (NOT function). On a NAND gate, the bubble follows an AND structure, explicitly indicating that the combined AND gate's output is inverted (complemented). Therefore, option A is the correct choice.
