Abstract
The paper is devoted to computational aspects ofthe problems of realization of discrete-time nonlinearsingle-input single-output composite systems. The maincontributions are made in two directions. First, we study therelations between three different methods that for anynon-realizable system construct a "compensating system" which willresult in a realizable series or parallel connection. Second, weimplement these methods and algorithms in the computer algebrasystem Mathematica. Results are illustrated by examples.
