Bridged Reactance-Resistance Networks
G.R. Harris · Proceedings of the IRE · 1949
Consideration is given to the various possible six-arm, six-element RC bridged networks of which the parallel-tee is the previously known example. It is found that six symmetrical RC structures exist having the infinite attenuation property of the parallel-tee and other properties differing from those of this structure. The duality of certain pairs of such structures is demonstrated.
