The phase lag produced by transportation relays_____________?
Correct answer: C. increases linearly with frequency
- A. is independent of frequency
- B. is inverseh'proportional to frequency
- C. increases linearly with frequency
- D. decreases linearly with frequency
Explanation
A transportation delay of T seconds has transfer function e^(-sT), whose phase is -ωT radians. Therefore, the phase lag increases linearly with frequency, not inversely with it.
