Bandlimited Functions Sampling and the Discrete Fourier Transform, however, not always possible or for that matter even necessary. Nevertheless, the subject is best introduced by starting with the idea of sampling. For this purpose we shall initially restrict the class of analogue signals which we propose to sample to so-called bandlimited functions.

Bandlimited Functions Sampling and the Discrete Fourier Transform,referred to as analogue signals. In this chapter we introduce the important topic of discrete signals, i.e., signals that are represented by sequences of numbers. Sometimes these numbers can be interpreted as samples of a continuous signal taken at discrete time intervals. Such an interpretation is,

pter 5 relies heavily on analytic function theory as does Chapter 8 on Z -transforms. The necessary background on complex variables is provided in Appendix A. .This book is intended to serve as a text on signals and transforms for a first year one semester graduate course, primarily for electrical engineers.978-1-4899-8710-5978-1-4614-3287-6

Wasyl Wasylkiwskyjy 2014, still in power, celebrated his ninetieth birthday in lavish style and with defiant rhetoric, in a country reduced to a shadow of its former self, with perhaps one third of its population having fled abroad. Such contrasting styles of leadership in Southern Africa provoke reflection on the ki
