A universal method for the symbolic representation of cascade connected two-port networks

Standard matrix methods were shown in [1] to be unsuitable for the symbolic representation of cascade connected two-port networks (quadrupoles) when at least one of the branches has an infinite impedance. In this paper, we give a further development of the previously proposed representation of cascade connected twoport networks, and show that the method is valid for any values of the branch impedances, both finite and infinite.
