Update : I would like a detailed view of how to represent using negative logic.

Negative logic is just like positive logic, only the desired output is a logic 0 instead of a logic 1. For example, an AND gate gives a logic 1 for both inputs being logic 1. A NAND gates gives a logic 0 for both inputs being a logic 1.

Simple as that! Just assume the desired output, when the input conditions are met, is a 0 instead of a 1.

    In negative logic, logic 1 ls a low and logic 0 is a high, so just replace L with 1 and H with 0 and simplify the same way
