The amplitude ratio for the sinusoidal response of a _____________ is 1?
Correct answer: C. Transportation lag
- A. First order system
- B. Second order system
- C. Transportation lag
- D. None of these
Explanation
A pure transportation lag only delays a sinusoidal signal and does not change its amplitude, so its amplitude ratio is one. First- and second-order systems generally attenuate or otherwise modify amplitude with frequency.
