Abstract
A system relationship function is defined which describes the “external response” of a set of coupled linear components in an electrical circuit. A differential equation system is defined for the set of coupled linear components, and a predetermined number of eigenvalues are determined for the homogeneous differential equation system. An error is indicated for the eigenvalues which is caused by ignoring those eigenvalues which have not been determined within the homogeneous differential equation system. If the error is less than a given setpoint error, then the system relationship function is produced from the differential equations which are described by the determined eigenvalues. If the error is greater than the limit, then further eigenvalues are determined, for which an error is in turn determined. This method is continued iteratively until the error is less than the limit.
