Question

The following statements refer to the pole-zero configuration for compensator networks: I. In lag network, pole is nearer to origin
II. In lag network, zero is nearer to origin
III. In lead network, zero is nearer to origin
IV. In lead network, pole is nearer to origin
Choose the correct combination:

• A. Only I is correct
• B. Only III is correct
• C. Only I & II are correct
• D. Only III & IV are correct

Hint:

Remember: - Lead → Zero closer to origin - Lag → Pole closer to origin

Answer 1

The Correct Option is D

- In a lead compensator, zero is closer to origin than pole (pole is further away).
- In a lag compensator, pole is closer to origin than zero.
Hence, only statements III and IV are true.
