(Sample)Transfer Function

G(s)=

s²

s²+12500s+39062500

R1 = 16kΩ
R2 = 16kΩ
C1 = 0.01uF
C2 = 0.01uF

Cut-off frequency
    fc = 994.718394324[Hz]

Quality factor
    Q = 0.5

Damping ratio
    ζ = 1

Pole(s)
    p = -994.718394324 +2.59971382044E-06i[Hz]
          |p|= 994.718394324[Hz]
    p = -994.718394324-6.59896406561E-07i[Hz]
          |p|= 994.718394324[Hz]

Zero(s)
    z = 0[Hz]
          |z|= 0[Hz]
    z = -0[Hz]
          |z|= 0[Hz]

Phase margin
    pm= NAN[deg] (f =0[Hz])

The system does not oscillate.

Overshoot (in absolute value)
    The 1st peak  g_pk = -0.14 (t =0.00033[sec])

Final value of the step response (on the condition that the system converged when t goes to infinity)
    g(∞) = 0
