The graphical solutions to some simple impedance networks, including L, T, and π configurations are presented here together with the analytic derivations. These graphs are helpful in visualizing the values of the circuit elements in designing impedance matching networks. Based upon these circuits, the constructions depend primarily on conversions between parallel and series circuits that are accomplished by means of straight lines instead of semi-circles as described previously by McNally and Keen.
