The task of an approximation of a continuous model according to obtained discrete data in its connection with Laplas transformation and z-conversion has been considered.
We found that the connection between ordinary differential equations and difference equations has analogy with inverse agreed z-conversion when transferring from complex z-plane to s-plane.
A comparative analysis classical techniques and the offered method of the transition from continuous to discrete model (and vice versa) has been performed.
