Calculation of the frequency responses of complex systems directly from the physical parameters

Abstract

The paper describes a novel technique by which frequency responses can be calculated. It works directly from the most basic physical data of the system, and, as such, even complex systems can be rapidly modelled and analysed. The method and its associated digital computation are inclined towards a control- engineering approach in which systems are represented by block diagram, but it will give the frequency- domain solution for any set of linear simultaneous differential equations. Examples are given for both forms of system representation to illustrate the practical use of the technique.
