Which logic gate is represented by the following combination logic gates?

Step-by-step solution

The given circuit consists of two NOT gates followed by a NOR gate. Let the inputs be A and B . The output of the first NOT gate is A . The output of the second NOT gate is B . These two signals are fed into a NOR gate. The output Y of a NOR gate with inputs X₁ and X₂ is X₁ + X₂ . Substituting X₁ = A and X₂ = B , we get Y = A + B . Using De Morgan's Law, A + B = A B = A B . The expression Y = A B represents the AND logic gate. Answer: AND
