1.80 For the circuit shown in Fig. P1.80, first evaluate Ti(s) = Vi(s)/Vs(s) and the corresponding cutoff (corner) frequency. Second, evaluate To(s) = Vo(s)/Vi(s) and the corresponding cutoff frequency. Put each of the transfer functions in the standard form (see Table 1.2), and combine them to form the overall transfer function, T(s) = Ti(s) × To(s). Provide a Bode plot for |T(jω)|. What is the bandwidth between 3-dB cutoff points?
