Negative Logic System Graph
Positive and Negative Logic - definitions If the more positive of the two voltage or current levels represents a logic '1' and the less positive of the two levels represents a logic '0', then the logic system is referred to as a positive logic system.
The definition of a state being positive logic or being negative logic is arbitrary and is dependant upon how the inputs are defined. So thinking about the problem in only 've terms is misleading. You choice the polarity of your logic based upon available logic gates and how easily you can express your problem. Sometimes certain gates are faster, smaller or even just available. And simple

The opposite is also true. Logic circuits are generally divided into two broad classes according to their polarity positive logic and negative logic. The voltage levels used and a statement indicating the use of positive or negative logic will usually be specified on logic diagrams supplied by manufacturers.

This document discusses positive and negative logic, integrated circuits, and digital logic families. It begins by defining positive and negative logic systems and providing examples of positive and negative logic gates. It then discusses how integrated circuits are constructed and classified by levels of integration from small to very large scale. Finally, it covers characteristics used to
The Negative Logic gates operation is the same as that of Positive Logic gates, but the actual gate symbol looks different. You can't go to an electronics parts supplier and ask for a Negative logic gate. It doesn't exist as a part. The concept of Negative Logic is a state of mind or a way of looking at the gate
The terms positive logic and negative logic refer to two conventions that dictate the relationship between logical values and the physical voltages used to represent them. Unfortunately, although the core concepts are relatively simple, fully comprehending all of the implications associated with these conventions requires an exercise in lateral thinking sufficient to make even the strongest
Negative logic inputs and outputs are called active low. Input and output polarity is indicated by a bubble or triangle. For example, the following shows a positive logic AND gate and a negative logic OR gate. But the system of digital logic where binary 0 represents higher voltage and binary 1 represents low voltage is called negative logic.
Positive Logic Negative Logic Now, let us discuss, the positive and negative logic in detail. As discussed above, in digital systems, the variables associated with operations can have only two values, i.e. 0 and 1. Where, 0 and 1 represents the OFF Logic LOW and ON Logic HIGH state of the system respectively. What is Positive Logic?
