The magnitude of frequency response of an under-sampled second order system is 5 at 0 rad/sec and peaks to 10/√3 at 5√2 rad/sec. The transfer function of the system is

\(\frac{{375}}{{\left( {{s^2} + 5s + 75} \right)}}\)

\(\frac{{245}}{{\left( {{s^2} + 1.21s + 49} \right)}}\)

\(\frac{{720}}{{\left( {{s^2} + 12s + 144} \right)}}\)

\(\frac{{1125}}{{\left( {{s^2} + 25s + 255} \right)}}\)
