Digital Systems Design with FPGAs and CPLDs

CHAPTER 5 Introduction to Digital Logic Design

5.1 Introduction

Although the world that we live in is analogue in nature, in electronic circuits and systems digital circuits are widely used and can be designed to perform many actions that were originally undertaken in analogue circuitry, as well as providing potential benefits over analogue circuit operation. The electronic system shown in Figure 5.1 will perform its operations on signals that are either analogue or digital in nature, using either analogue or digital electronic circuits [1]. Hence, a signal may be one of two types: analogue or digital.
