Z-Transform is one of several transforms that are essential _mathematical tools used in engineering and applied sciences. This _short edition of this note is written to provide an introduction to the _subject of Z-Transform. The material presented in this note can be _covered in four to five 2-hour classroom lectures. Basic knowledge of _calculus is needed. The note is not intended as a substitute for a text _book on the subject. It is intended to help readers and students in _engineering, mathematics and applied sciences understand the basic properties of Z-_Transform and some of the methods and techniques based on this _transform to solve some engineering and science problems._
I have collected many examples and problems on the subject _that might help the reader getting on-hand experience with the _techniques presented in this note._
