🔍 Key Concepts

• Negative logic vs positive logic in digital circuits • How logic 1 and logic 0 are mapped to voltage levels • What signal level (high or low) is assigned to each logic state in a negative-logic convention

💭 Think About

• In a normal (positive-logic) system, which voltage level usually represents logic 1 and which represents logic 0? • If negative logic reverses that assignment, what voltage level would then be used to represent logic 0? • Look at which answer choices describe actual voltage levels, not transitions between levels.

✅ Before You Answer

• Be clear on how positive logic maps logic 1 and 0 to high and low voltages. • Confirm that negative logic inverts that usual mapping between high/low and 1/0. • Eliminate options that refer to transitions (edges) instead of steady logic levels.
