Answer 1

Question:

Explain the terms positive and negative logics.

Answer:

Positive and negative logics simply refer to the logics used in a particular circuit or operation. These terms are usually used by engineers. It tells whether a positive or negative logic was used that is usually expressed in binary form.

Positive logic

It refers to circuits or actions that use logic 1. It means that positive signals are used and there is higher voltage.

Negative logic

It refers to circuits or actions that use logic 0. It means that negative signals are used and there is lower voltage.

Logic Level

It is one among the many states used to represent the the electrical ground that refers to the digital signal the ground can possess. They are expressed as DC voltage. There are 2 logic levels that are referred in binary forms [binary logics]- logic 1 and 0. The logic 1 possess positive charges and has more voltage while the logic 0 possess negative charges and has less voltage.

Answer 2

Answer:

1. Positive logic is defined as a high voltage level representing a logic 1 and a low voltage level representing a logic 0.
2. When a circuit requires logic 1 to operate, engineers may refer to this condition as positive logic. Thus, the more positive voltage causes the action to take place.
3. Negative logic is the reverse, i.e., a low voltage level represents a logic 1 and a high voltage level represents a logic 0.
4. On the other hand, if a circuit requires a logic 0 to cause action, this type circuit is referred to as negative logic.
