Explanation

By De Morgan's laws, an OR gate in negative logic (where 0 is high and 1 is low) behaves as an AND gate in positive logic, and vice versa. Specifically, an OR gate with inverted inputs and output acts as an AND gate. A NOR gate in positive logic is equivalent to an AND gate in negative logic.
