Solutions of difference equations using Z-transform technique.

The aim of the thesis is to give a study about the z-transformation, which is one of the most important applicable implemented techniques for solving the discrete dynamic system. The basic concepts and theories of the z-transform technique is presented. Its implementation to obtain the solution of ordinary and delay linear difference equation is presented. The modification to z-transform technique has been attempted to solve the system of ordinary and partial linear-difference-differential equation The convolution z-transform technique has been implemented to obtain the solution of certain non-linear discrete system. And demonstrate the solution procedures implementation the Matlab software.
