This is a student supplement associated with: Electronic Communications: A System Approach, 1/e Jeffrey S. Beasley Jonathan D. Hymer Gary M. Miller ISBN: 0132988631

Now in its second edition, Electronic Communications Systems provides electronics technologists with an extraordinarily complete, accurate, and timely introduction to all of the state-of-the-art technologies used in the communications field today. Comprehensive coverage includes traditional analog systems, as well as modern digital techniques. Extensive discussion of today's modern wireless systems - including cellular, radio, paging systems, and wireless data networks - is also included. In addition, sections on data communication and the internet, high-definition television, and fiber optics have been updated in this edition to enable readers to keep pace with the latest technological advancements. A block-diagram approach is emphasized throughout the book, with circuits included when helpful to lead readers to an understanding of fundamental principles. Instructive, step-by-step examples using MultiSIM.

For courses in Electronic Communications Technology (one or two-semester sequence), Microwave Communications, Wireless Communications, Communications Maintenance Technology, and Introduction to Telecommunications. Electronic Communications: A Systems Approach provides a comprehensive overview of wireless, wired, analog, and digital electronic communications technologies at the systems level. The authors' carefully crafted narrative structure helps readers put the many facts and concepts encountered in the study of communications technologies into a larger, coherent whole. Topics covered include modulation, communications circuits, transmitters and receivers, digital communications techniques (including digital modulation and demodulation), telephone and wired computer networks, wireless communications systems (both short range and wide area), transmission lines, wave propagation, antennas, waveguides and radar, and fiber-optic systems. The math analysis strikes a middle ground between the calculus-intensive communications texts intended for four-year BSEE programs and the math-avoidance path followed by some texts intended for two-year programs.

* Experiments are linked to real applications. Students are likely to be interested and excited to learn more and explore. Example of experiments linked to real applications can be seen in Experiment 2, steps 6, 7, 15, and 16; Experiment 5, steps 6 to 10 and Experiment 7, steps 12 to 20. * Self-contained background to all electronics experiments. Students will be able to follow without having taken an electronics course. Includes a self-contained introduction based on circuits only. For the instructor this provides flexibility as to when to run the lab. It can run concurrently with the first circuits analysis course. * Review background sections are provided. This convenient text feature provides an alternative point of view; helps provide a uniform background for students of different theoretical backgrounds. * A "touch-and-feel" approach helps to provide intuition and to make things "click". Rather than thinking of the lab as a set of boring procedures, students get the idea that what they are learning is real. * Encourages students to explore and to ask "what if" questions. Helps students become active learners. * Introduces students to simple design at a very early stage. Helps students see the relevance of what they are learning, and to become active learners. * Helps students become tinkerers and to experiment on their own. Students are encouraged to become creative, and their mind is opened to new possibilities. This also benefits their subsequent professional work and/or graduate study.
