CHAPTER 1

Introduction

In general, sensors generate analog signals in response to various physical phenomena that occur in an analog manner (i.e., in continuous time and amplitude). Processing of signals can be done either in analog or digital domain. To do the processing of an analog signal in digital domain, it is required that a digital signal is formed by sampling and quantizing (digitizing) the analog signal. Hence, in contrast to an analog signal, a digital signal is discrete in both time and amplitude. The digitization process is achieved via an analog-to-digital (A/D) converter.

Digital signal processing (DSP) involves the manipulation of digital signals in order to extract useful information from them. Although an increasing amount ...
