There are many reasons that one might prefer to use negative logic in some or all of a design, a few of these are:
Mostly Japanese prefer negative logic so you can face negative logic in Japanese equipment only
A positive logic system will output true only when the input is true. A negative logic system will output true only when the input is false. The NOT logic gate is an example of a negative logic system. That is, NOT( false ) will output true.
could be negative or positive"negative logic" just means, that the level used by "positive logic" within that logic family for False, is instead used for "True" and vice versa.
A positive logic system will output true only when the input is true. A negative logic system will output true only when the input is false. The NOT logic gate is an example of a negative logic system. That is, NOT( false ) will output true.
negative logic means negative input values. so by checking the truth table, it becomes an OR gate

In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
act of making statement: in logic, the mental act of making or understanding a positive or negative proposition about something.-Michael Tuazon-
there is booklet called IMP that explains it very VERY CLEARLY using fire cubes and Ice cubes. You need to see the drawing for it to make sense. Look it up as IMP
Positive logic ON = 1, OFF = 0. Negative logic ON = 0, OFF = 1.
Only if you decide to work with negative logic throughout the circuit.
In a circuit where true is represented by logic 0 and false by logic 1, the logic is referred to as "inverted" or "negative logic." This means that the conventional interpretation of truth values is reversed, with low voltage levels indicating true and high voltage levels indicating false. This approach can be useful in certain digital systems and simplifies the design of certain types of circuits, particularly in memory and logic gate implementations.
