Synthesis of cable simulation networks

This tutorial paper describes a simple design procedure which permits excellent simulation of cable performance employing a symmetrical lattice network containing a small number of elements. The problem is reduced to one of synthesizing 2-terminal impedances at two frequencies. The design technique is illustrated with applications to three lengths of a particular cable. The performance covering more than 2 decades of frequency shows a design error of less than 0.5% in both real and imaginary parts of the image impedance and propagation constant of the cable. With the aid of loading coils, such networks can be used to simulate the transmission characteristics of any type of loaded cable facility having any fractional length of end section.
