Photonic Signals and Systems: An Introduction

CHAPTER 1Introduction

Why You Should Read This Book

The modern world is exploding with omnipresent signal flow. Some signals are visible to us as humans, whereas others flow quietly in hidden channels. These signals typically are interconnected with systems that perform specific functions. For example, some systems implement the task of communications, whereas others enable object detection, such as identification of specific human diseases or fast-moving airplanes. Some systems help us measure vital parameters, such as temperatures in power-plant turbines, whereas others measure chip thickness in semiconductor processing of computer chips. In short, the modern world is highly engaged with signals crisscrossing continents, cities, offices, homes, ...
