Two-port equivalences for bandpass filters

This brief describes a set of equivalences to be used to implement one or two finite transmission zeros in a bandpass [inductance-capacitance (LC) or microwave] filter in the form of three or four grounded resonators with multiple coupling branches. A generalization of the Norton (impedance) transformation is also described for circuits that contain multiple coupling branches.
