Electronic Communication Systems: A Complete Course, Fourth Edition, addresses the variety, reality, complexity, and pervasiveness of today's communications systems. Our world is linked by often instantaneous voice, video, message, and data paths, and these links are getting faster, more complex, and more complete every day; many people are jaded even when they are presented with live photos and scientific data transmitted from other planets in our solar system. At the same time, existing communication systems such as the basic telephone and television continue to have a major role in setting standards for system behavior and compliance. New technologies such as network processors and Internet protocol are applied to older systems to improve performance, lower cost, and enhance features.

Engineers and technicians now deal with communication systems in three very different ways than they did even just a few years ago:

• Digital techniques and signals are used in nearly all new designs and systems, yet analog issues and characteristics continue to be an inherent and unavoidable part of the system design and challenge.
• Systems use sophisticated processors and software to implement signal- and data-processing algorithms and embed flexible functionality, making high-speed, low-error links practical and robust.
• Integrated circuits, which provide complete system functions on a single encased component with software-defined parameters, have largely supplanted circuitry that required many discrete support components, while also reducing overall size, cost, and power consumption.

Electronic Communication Systems: A Complete Course explores communications from the new perspective, while building on the foundation of older systems that are still in use. Students who use this book will understand much more than the circuits that implement systems. They will understand systems at the functional block diagram level; how systems are built with specific design tradeoffs and constraints; and how a system balances speed, performance, complexity, cost, and power consumption. Students will also see how troubleshooting at the system level is very different than troubleshooting at the component level, and will see the basic and sophisticated instruments that are needed for hands-on system investigation.

THE FOURTH EDITION

Since the third edition of the book appeared, the worldwide growth in all aspects of communications has been astonishing and exponential. Email links people scattered all over the globe, while the Internet provides enormous information and entertainment resources to anyone who has basic access. Cellular phones are ubiquitous, outnumbering conventional wired phones in some countries, and providing convenient voice and data access from almost anywhere.

The fourth edition builds on the new topics of the previous editions by adding or expanding on numerous topics, including fiber optics, optical amplifiers, and wavelength-division multiplexing; new buses and interconnection standards such as CAN bus; Internet Protocol and Voice over Internet Protocol; channel simulators and wireless noise characteristics; the short-range Bluetooth wireless standard; smart antennas for cellular systems; cell phone architectures that are primarily digital, using undersampling and oversampling; and the updated electromagnetic spectrum assignments.

As part of the revision for the fourth edition, the entire book was reviewed, with extensive expansion and adjustment, especially in the application chapters. The sections on networks, cellular systems, wireless and wired systems, and fiber optics were reevaluated in light of the enormous and rapidly accelerating changes that have occurred in these areas in just a few years. The fundamentals of spectrum, modulation, transmitters, receivers, cables, antennas, and digital concepts are covered as before. Over half the book is devoted to applications such as video, telephones, standard and DSL modems, RS-232 (and similar), cellular systems, networks, radar, Ethernet, the Internet and the World Wide Web, wired and wireless systems, satellites, Bluetooth, the Global Positioning System, and fiber optics.

For each application, we look at what it accomplishes, how it does this, the functional blocks and components it uses, what limitations it has, and what constraints and tradeoffs shape the application. Where standards define performance, we look at what the standard defines and why, as well as what it leaves open and where its often-deliberate gaps are. We also admit that in many cases, communications systems overlap, cooperate, and even compete with each other; for the long-term, some implementations will survive and others may not—only time and the market will tell.

Further, this edition addresses the important role of simulation in systems planning and analysis. In parallel with ICs as system-level building blocks, today's designers and technicians develop and understand systems and tradeoffs using software-based simulation tools which model communication functions at the block-diagram level, and then exercise these models in a simulation mode. This book includes a CD-ROM which contains a highly regarded, powerful, yet easy-to-use simulation package called SystemView by Elanix. With this software running on a PC, the student can quickly see, for example, how changing the filter bandwidth in the receiving-path front end affects the final bit error rate, regardless of the specific circuits used to build the system.

In-Text Learning Aids

Electronic Communication Systems: A Complete Course, Fourth Edition, was designed with the beginning student in mind. Each chapter opens with Chapter Objectives contained in a color box and an Introduction. Review Questions follow each chapter section and serve to reinforce what the student has just learned. Color is used to highlight important elements in the illustrations. Within each chapter, clearly marked, worked-out solutions are provided for numerical examples. Each chapter concludes with a Chapter Summary (corresponding to the Chapter Objectives), Summary Questions, and numerical Practice Problems (broken down by chapter section).

To provide historical perspective, explore a subject in more depth, or go slightly off the mainline path of a chapter, the book uses sidebars to present additional material. Sidebars provide the student with interesting additional information that is not essential to the basic flow of the chapter but adds new facets to the student's understanding of the topic.

The Supplement Package

Careful thought was put into developing a comprehensive and useful set of free supplementary teaching aids for instructors:

• The Instructor's Resource Manual provides teachers with additional numerical problems and applications, worked-out solutions to these additional problems as well as to those found in the text, chapter outlines for each chapter, and a CD containing PowerPoint slides of all illustrations from the text. Available to instructors only.
• A Test Item File, compiled by Paul Perletti (Mount Hood Community College, Portland, OR), offers approximately 100 problems for each chapter to be used in preparing exams. Available to instructors only.

A DEDICATION

In communications, one person stands out through his far-reaching, long-lasting contributions. Major Edward H. Armstrong (1890-1954) conceived, analyzed, produced, and perfected several major innovations. Two of these—the superheterodyne receiver and FM transmission—are still vital to communications systems in this advanced age of digital electronics, microprocessors, and ICs; his first invention—the regenerative amplifier—allowed vacuum tubes in amplifiers to have much greater effective gain for weak signals (although subsequent developments have made it obsolete).

This book encompasses the world of digitally driven, microprocessor-based analog and/or digital communication while recognizing the efforts and legacy of persons such as Major Armstrong.
