Sampling Theory for Control Engineers

This paper is intended to serve as an introductory reading for practicing control engineers with little or no background in sampling theory. The topics are introduced in a non-rigorous manner utilizing many examples. Some important terminologies of sampling theory are explained. Basic statistical techniques important to control engineers are discussed in two parts. The first part involves the mean while the second part deals with the variance. Some ``quick and dirty'' methods together with some ``standard'' techniques are presented. An example of a particular application is also included.
