The resultant logic gate from the combination of following gates is

Step-by-step solution

Circuit Analysis The circuit consists of two NOT gates followed by a NOR gate with inputs A and B . The first NOT gate inverts input A , producing A' . The second NOT gate inverts input B , producing B' . These signals are fed into a NOR gate, yielding output Y = (A' + B')' . Applying De Morgan's theorem, (X + Y)' = X' Y' , so Y = (A')' (B')' . Since double inversion returns the original variable, (A')' = A and (B')' = B , so Y = A B . This is the Boolean expression for an AND gate.
