Abstract : The assumption of ideal elements places a practical limitation on the theory of Modern Network Synthesis. To extend the theory to cope with more realistic elements, several new classes of threeelementkind networks were studied. Realizability conditions were derived for drivingpoint impedances of these networks. This was achieved through physical arguments leading to a property of drivingpoint functions which was called the difference function. It was shown that the positiveness of the difference function over an appropriate portion of the splane represents a necessary and sufficient condition for a rational function to be realizable as the drivingpoint impedance of a given network class. The most notable contribution was perhaps the establishment of a general theory for networks composed of resistances and reactances with semiuniform loss (i.e., all inductors have one Q; all capacitors have another Q). This theory is almost as comprehensive as that now available for RLCT networks. (Author)
