Q. 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
Correct : Option (D)

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.
