→Vout(s)
(Sample) Transfer Function:
G(s)= 6283.18530718
s+6283.18530718


Cut-off frequency
    fc = 1000[Hz]


Final Vout value of the step response (without a ripple)
    g(∞) = 2.5[V]


Peak-to-peak ripple voltage
    ΔVpk-pk = 0.779001646108[V](Duty=50%)


Settling time 0%→90% (0V→2.25V) (without a ripple)
    tr = 0.00036646779944[sec]
