The logic operations performed by the given digital circuit is equivalent to:

Options

  1. ANOR
  2. BAND
  3. COR
  4. DNAND

Correct answer

B. AND

Step-by-step solution

As shown in the figure the various logic gates have been mentioned. Let the output before the N O T gate be Z . Using the expression for the logic gates, it can be written Z = A + B · ( A · B ) Hence, the output Y is Y = Z = A + B · ( A · B ) ⇒ Y = A · B Hence the digital circuit is equivalent to an A N D gate.
