The realization of dissipative reactance two-port networks is proceeded by combining network system of ZRZLZCT and concept of predistortion of ideal two-port networks. This has presented a clearer physical understanding and has led to some significant results. In addition

new ideas and methods hive been suggested in the formulation of the transfer function and in the solution of open-circuit impedance parameters. With simple termination impedances at two-ports

formula have been obtained for the calculation of parameters of open-circuit impedances.
