In an all NOR gate realization of a combinational circuit all EVEN and ODD level gates behave like
- A. OR and AND
- B. AND and OR
- C. OR and NOT
- D. NOR and AND
Answer: B. AND and OR
Explanation: In NOR-NOR realization of combinational logic, odd level gates act as OR and even level gates act as AND, or equivalently alternate levels act as AND and OR logic.
