With the increased usage of sampled-data systems, the ability to analyze such systems in a rapid, accurate manner has become more important. Unfortunately, however, the conventional approach to the analysis envolves methods of approximation and the analysis of such systems by hand is a tedious and time consuming process thus making an accurate investigation of system variables difficult.

With this in mind, the purpose of this project has been to create a flexible computer based method for rapid, accurate and extensive investigation of a variety of sampled-data systems. The method employed in this computer package is the "Z" transform technique as defined by the complex convolution integral and the Residue theorem. A general configuration of a sampled-data system in the Laplace domain under the influence of a unit step forcing function, is assumed. The computer package transforms this system into the "Z" domain and provides the option of Transient Time Response and Root Locus analysis. These two options are offered because, from the standpoint of a systems analyst, accurate knowledge of the transient response is essential in time-domain testing and the root locus provides valuable insight into the system's stability, frequency and transient response, and steady state behavior.
