The reader may believe that this is an outdated technology. However, it is stillbeingusedandmoreimportantlythetheorybehindalladvancedfilter structures is based on passiveLC filters. This is also the case for digital and switched-capacitor filters. The reader is strongly recommended to carefully study the principle of maximum power transfer, sensitivity to element errors, and the implications of Equation (3.26).
