If a second-order network has alpha=2 rad/s and omega0=5 rad/s, its natural response is?

  • AOverdamped
  • BCritically damped
  • CUnderdamped
  • DNoncausal
Report an error
Correct Answer: C. Underdamped
Explanation: Since alpha<omega0, the characteristic roots are complex conjugates and the response is underdamped.
