    pm= NAN[deg] (f =0[Hz])


The system does not oscillate.


Overshoot (in absolute value)
        The 1st peak  gpk = 0.12 (t =0.00012[sec])


Final value of the step response (on the condition that the system converged when t goes to infinity)
    g(∞) = 1
f0=Hz
C1 = F C2 = F C3 = F
C1, C2, C3 is optional. But when setting these capacitances, C1, C2 and C3 of all are needed to give.
