In negative logic:
  • logic 0 = Some positive voltage
  • logic 1 = Zero voltage
or
  • logic 0 = Some higher voltage level (i.e. + 5 V,)
  • logic 1 = Some lower voltage level (i.e. + 2 V)

Negative logic in a logic circuit refers to a system where logic 0 and logic 1 voltage levels are defined in a way that logic 0 voltage level is higher than the logic 1 voltage level. This is the correct answer according to option 'D'. Let's understand this in detail.

Negative logic is a convention used in some logic circuits where logic 0 is represented by a higher voltage level than logic 1. In this system, the voltage levels are reversed compared to the more common positive logic convention, where logic 0 is represented by a lower voltage level than logic 1.

Explanation:
1. Logic 0 and Logic 1:
- In digital circuits, logic 0 represents a low voltage level (usually near 0V) and logic 1 represents a high voltage level (usually near the supply voltage).
- In positive logic, logic 0 is represented by a lower voltage level and logic 1 is represented by a higher voltage level.
- In negative logic, the convention is reversed, where logic 0 is represented by a higher voltage level and logic 1 is represented by a lower voltage level.

2. Voltage Levels in Negative Logic:
- In a negative logic system, logic 0 is represented by a higher voltage level, which is typically closer to the supply voltage.
- Logic 1 is represented by a lower voltage level, which is typically closer to 0V or ground.
- This reversal of voltage levels can be due to various reasons, such as design requirements or compatibility with existing systems.

3. Example of Negative Logic:
- Let's consider an example of a simple logic circuit using negative logic, such as an inverter (NOT gate).
- In positive logic, the input voltage of 0V would result in an output voltage of the supply voltage (logic 1) and an input voltage of the supply voltage would result in an output voltage of 0V (logic 0).
- In negative logic, the input voltage of the supply voltage would result in an output voltage of the supply voltage (logic 0) and an input voltage of 0V would result in an output voltage of 0V (logic 1).

Conclusion:
Negative logic in a logic circuit refers to a system where logic 0 is represented by a higher voltage level than logic 1. This convention is different from the more common positive logic, where logic 0 is represented by a lower voltage level. Understanding the voltage levels and their representation in a given logic system is essential for proper circuit design and analysis.
