Abstract

The paper is concerned with the properties of z-transform and its inverse for the solution of certain types of difference equations. The procedure involves the reduction of the difference equation to an algebraic equation using the properties of z- transform. The equation is then solved using algebraic techniques and subject to the governing boundary conditions. This process is illustrated with a solution of the Fibonacci sequence and other examples from various fields of science and economics.

Keywords: z-transforms, residue, power series, partial fractions, Fibonacci sequence
