Question

\text { A plant transfer function is given by } G(s)=\frac{X(s)}{U(s)}=\frac{1}{2 s+1} \text {. } a) Determine the gain cut-off frequency of G(s). b) If G(s) is subjected to an

input excitation signal u(t)3 sin 100t + 8 sin 0.001t, state,with reasons, what the steady state output signal would be.
