A phase lag lead network introduces in the output_______________?
Correct answer: C. lag at low frequencies and lead at high frequencies
- A. lag at all frequencies
- B. lag at high frequencies and lead at low frequencies
- C. lag at low frequencies and lead at high frequencies
- D. none of the above
Explanation
A lag-lead network contributes lag at low frequencies and lead at high frequencies, combining improved steady-state accuracy with improved transient response. Therefore option c gives the standard frequency-wise description.
