XXVI. A note on Duhamel's integral, with particular reference to the transient response of cascaded filter sections
David Gorda Tucker · The London Edinburgh and Dublin Philosophical Magazine and Journal of Science · 1948
Summary The superposition theorem is generally applied by means of Duhamel's integral, and it is shown that the solution of practical transient-response problems may be aided by the use of power-series in this integral. This enables a generalized power-series expression of the output transient from cascaded circuits to be obtained, and the method is used to determine the build-up response of cascades of Zobel-type filter sections.
