Which one of the following methods can determine the closed loop system resonance frequency operation?
A. Root locus method
B. Nyquist method
C. Bode plot
D. M and N circle
Answer:D
Which one of the following methods can determine the closed loop system resonance frequency operation?
A. Root locus method B. Nyquist method C. Bode plot D. M and N circle
Explanation: Closed loop system resonance frequency is the frequency at which maximum peak occurs and this frequency of operation can best be determined with the help of M and N circle.
