Telegrapher's equation
An analytical solution of the coupled Telegrapher's equations for the voltage and current on a homogeneous lossy transmission line is presented. The resulting expression is obtained in the form of an exact time-domain propagator operating on the line voltage and current. It is shown that an application of Simpson's rule yields a simple accurate numerical representation of the propagator that ...time step of the numerical analysis, a non-linear equation is solved to obtain the values of currents and voltages at each spatial step.

Maxwell's equations for an infinite, lossless tra The Telegraphers' Equations come from a transmission line model, answering the question, "if I impose a time-varying voltage on one side of the transmission line (the input), what happens on the other side (the output)?" The lumped element model represents an infinitesimally small section of a transmission line. As was studied some years ago in Ref. , the telegrapher’s equation, like the diffusion equation, can also be derived from the Chapman-Kolmogorov equation, which is the master equation for Markovian processes .
