Abstract

The present chapter presents a brief overview of some key aspects of the theory of signal processing trying as much as possible to interconnect them. We start by discussing the basic concepts related to the continuous- and discrete-time signals and systems with emphasis on the latter. Then several basic concepts of discrete-signal representation, signal quantization, filter design and implementation are discussed in order to review the basic fundamentals of the classical digital signal processing ...
