MCQ
In positive logic, the logic state $1$ corresponds to:
- APositive voltage
- BZero voltage
- CLower voltage level
- ✓Higher voltage level
✓
Answer
Correct option: D.
Higher voltage level
In digital logic, higher voltage is defined as logic state $'1\ '$ and lower voltage is defined as logic state $'0\ '$. The higher voltage need not necessarily be positive. For example, it is possible that state $'0\ '$ is defined as $−10 V$ and state $'1\ '$ is defined as $−5 V.$
