Consider the Nyquist plot of the second-order underdamped system shown in the below figure The resonant frequency corresponding to the Nyquist plot is Correct Answer ω<sub>2</sub>
Concept:
Resonance
- The frequency at which circuit operates at its natural frequency is called resonant frequency.
- At the resonance, Magnitude will be highest.

- Magnitude is the length of phasor drawn from the origin.
Conclusion :
From the given plot it is visible that length of phasor from origin to ω2 is the highest so it acts like resonant frequency.
