R. Parthasarathy, K.N. Jayasimha · Electronics Letters · 1982
An algorithm to obtain the Cauer continued-fraction expansion of a given transfer function about an arbitrary point s = a and s = ∞ alternately is presented. Its application to system reduction is discussed. The procedure is amenable to digital computation.
