“…The motivation and interest for the study of various families of generating functions lie in their role in the investigation of various potentially useful properties and characteristics of the sequences which they generate. In the form of Z-transforms, which essentially are the discrete counterparts of the Laplace transform, generating functions are used in converting difference equations of discretetime signals and systems into algebraic equations, thereby providing simplifications in discrete-time system analysis, and also in a wide variety of problems involving sequential fractional-order difference operators, operations research and other areas of applied sciences (including, for example, queuing theory and related stochastic processes) (see, for details, [36] and the references which are cited therein).…”
