Consider again the simple RL circuit shown in Fig. 9.5 (Example 9.1). The transfer function of the RLcircuit is G(s)=\frac{I(s)}{E_{\mathrm{in}}(s)}=\frac{1}{L s+R} where the output is current /(1) and the input

is source voltage e(t). If the system parameters are L = 0.02 Hand R = 1.5 ohms determine the bandwidth (in hertz, Hz) of the RL circuit.
