*1.79 A voltage amplifier has the transfer function Using the Bode plots for low-pass and high-pass STC networks (Figs. 1.23(a) and (b) and 1.24(a) and (b)), sketch a Bode plot for |Av|. Give approximate values for the gain magnitude at f =10 Hz, 102 Hz, 103 Hz, 104 Hz, 105 Hz, 106 Hz, 107 Hz, and 108 Hz. Find the bandwidth of the amplifier (defined as the frequency range over which the gain remains within 3 dB of the maximum value).
