The circuit in Fig. 15.70 is known as a “notch” filter, used to remove a narrow range of frequencies (for example, an undesired resonance). (a) Determine the transfer function for this circuit; (b) plot the magnitude Bode plot for this filter; (c) determine the center frequency for the notch filter and the reduction in magnitude at the center frequency (in dB).
