A comparison of the transform and classical methods

This article compares the amount of arithmetical computation required to determine transient currents by the transform method with that required to determine the same currents by the classical method. The amount of arithmetical computation is measured by the number of times it is necessary to multiply or add two numbers. Comparison is made only for the case in which the circuits have few branches with lumped constants of resistance, inductance, and capacitance, and any advantage or disadvantage either method may have in other cases is not considered. No account is taken of the added effort necessary to acquire a working knowledge of the transform method nor of the time required to derive the transform expressions for the currents from the differential equations.
