on wireless, n etworking, and other communications technologies. Because the fi eld of electronic c ommunications changes so fast, it is a never-ending challenge to keep a textbook up to date. While principles do not change, their emphasis and relevance do as technology evolves. Furthermore, students need not only a fi rm grounding in the fundamentals but also an essential understanding of the real world components, circuits, equipment, and systems in everyday use. This latest edition attempts to balance the principles with an overview of the latest techniques. A continuing goal of this latest revision is to increase the emphasis on the system level understanding of wireless, networking, and other communications technologies. Because of the heavy integration of communications circuits today, the engineer and the technician now work more with printed circuit boards, modules, plug-in cards, and equip- ment rather than component level circuits. As a result, older obsolete circuits have been removed from this text and replaced with more integrated circuits and block diagram level analysis. Modern communications engineers and technicians work with specifi cations and standards and spend their time testing, measuring, installing, and troubleshooting. This edition moves in that direction. Detailed circuit analysis is still included in selected areas where it proves useful in understanding the concepts and issues in current equipment. In the past, a course in communications was considered an option in many elec- tronic programs. Today, communications is the largest sector of the electronics fi eld with the most employees and the largest equipment sales annually. In addition, wire- less, networking, or other communications technologies are now contained in almost every electronic product. This makes a knowledge and understanding of communica- tion a must rather than an option for every student. Without at least one course in communications, the student may graduate with an incomplete view of the products and systems so common today. This book can provide the background to meet the needs of such a general course. As the Communications Editor for Electronic Design Magazine (Penton), I have observed the continuous changes in the components, circuits, equipment, systems, and applications of modern communications. As I research the fi eld, interview engineers and executives, and attend the many conferences for the articles and columns I write, I have come to see the growing importance of communications in all of our lives. I have tried to bring that perspective to this latest edition where the most recent techniques and technologies are explained. That perspective coupled with the feedback and insight from some of you who teach this subject has resulted in a textbook that is better than ever. New to this Edition Here is a chapter-by-chapter summary of revisions and additions to this new edition. Chapters 1–6 Updating of circuits. Removing obsolete circuits and adding current circuits. Chapter 7 U pdated section on data conversion, including a new section on overs- ampling and undersampling. viii Chapter 8 Expanded coverage of the I/Q architecture for digital data transmis- sion.

Addition of AWGN and expanded coverage of intermodulation distortion. Increased coverage of the software- defi ned radio (SDR). New IC receiver circuits and transceivers. Chapter 10 Updated coverage of multiplexing and access techniques. Chapter 11 Expanded coverage of digital modulation and spectral effi ciency. Increased coverage of digital modulation schemes. New coverage of DSL, ADSL, and VDSL. Addition of cable TV system coverage. Improved coverage of the OSI model. Addition of an explanation of how different digital modulation schemes affect the bit error rate (BER) in communications systems. Updated sections on spread spec- trum and OFDM. A new section on convolutional and turbo coding and coding gain. Chapter 12 Heavily revised to emphasize fundamentals and Ethernet. Dated mate- rial removed. Expanded and updated to include the latest Ethernet stan- dards for fi ber-optic and copper versions for 100 Gbps. Chapter 13 Minor revisions and updates. Chapter 14 M inor revisions and updates. Chapter 15 Fully updated. Addition of coverage of IPv6 and the Optical Transport Network standard. Chapter 16 U pdated with new emphasis on millimeter waves. Updated circuitry. Chapter 17 R evised and updated. Chapter 18 Removal of dated material and updating. Chapter 19 E xpanded section on MSA optical transceiver modules, types and specifi cations. OM fi ber added. Addition of coverage of 100-Gbps techniques, including Mach-Zehnder modulators and DP-QPSK modulation. Chapter 20 E xtensively revisions on cell phone technologies. New coverage on HSPA and Long Term Evolution (LTE) 4G systems. Analysis of a smartphone. Backhaul. A glimpse of 5G including small cells. Chapter 21 U pdates include addition of the latest 802.11ac and 802.11ad Wi-Fi standards. New coverage on machine-to-machine (M2M), the Internet of Things (IoT), and white space technology. Chapter 22 Revisions and updates include a new section on vector signal analyzers and generators. One major change is the elimination of the ineffective chapter summaries. Instead, new Online Activity sections have been added to give students the opportunity to further explore new communications techniques, to dig deeper into the theory, and to become more adept at using the Internet to fi nd needed information. These activities show students the massive stores of communications information they can tap for free at any time. In a large book such as this, it’s diffi cult to give every one what he or she wants. Some want more depth, others greater breadth. I tried to strike a balance between the two. As always, I am always eager to hear from those of you who use the book and welcome your suggestions for the next edition. Preface ix
