What is the damped frequency of oscillation (omega_d) for a system with poles at s = -3 +/- j4?
Explanation
For an underdamped second-order system with complex poles at -sigma_d +/- j*omega_d, the imaginary part, omega_d, directly gives the damped frequency of oscillation, which is the frequency of the decaying sinusoidal component of the time response.
