Which of the following gate give the similar output as the output of circuit diagram shown in the figure?

Step-by-step solution

A and B pass through buffers (output unchanged), then enter an OR gate. Output of OR gate: A + B This passes through another buffer, remaining A + B . The final AND gate takes three inputs: (A+B) , A , and B . Y = (A+B) A B Applying distributive law: Y = (A A B) + (B A B) Applying idempotent law ( A A = A , B B = B ): Y = (A B) + (A B) = A B The circuit is equivalent to an AND gate.
