A novel summation approach in technique to find the transient response

A pulse is developed by discharging an initially charged lossless transmission line through a load, as shown. A novel summation variation on the usual computation by multiple reflections of the transient response for a realistically modeled pulse generator loaded with different kinds of loads is described. This constitutes an alternative method for evaluation of the inverse Laplace transform applicable for general lumped loads. As examples, we employ this approach to calculate the transient voltage response for a constant resistance and a parallel RC combination loads. The results obtained using this technique are compared with those obtained by superposition of multiple reflections.
