On analysis of pulse signal propagation based on transfer functions of lumped distributed multi-branch coupled line networks

First, network transfer functions of lumped distributed multi-branch networks are described from signal flow graph techniques. Next, a cascade connection of three multi-branch networks is discussed. This includes all the factors necessary for the analysis of interconnected networks consisting of more than four multi-branch networks. Lastly, an interconnected network consisting of three multi-branch networks which includes a coupled line section is taken up, and its step responses are calculated using a program of FLT and network functions of this paper. Comparison with other paper's results shows good agreement.
