Bill Schweber, the author of this excellent 800-page textbook, is well-known to readers of EDN magazine (and earlier, to readers of Analog Dialogue). His writing is characterized by clarity of exposition and a practical approach. In the preface to the first edition, he set out his theme: to cover the traditional aspects of communications, yet recognize and explore three factors that have changed the face of communications systems: the widespread use of ICs to implement circuitry, the use of microprocessors and software to manage and improve the operation of traditional analog communication systems, and the use of digital techniques and signals to supplement or virtually replace analog techniques. The book provides a presentation of the way systems are commonly implemented, along with a discussion of the tradeoffs that exist in any system design: speed, power, performance, errors, complexity.

Over half the first edition was devoted to digital communications and actual communication systems­video, facsimile, telephone, modems, RS-232, cellular phones, computer networks, satellites, radar, fiber optics (following the necessary basic topics, such as bandwidth AM, FM, antennas, transmitters, receivers, and microwaves). The new edition has expanded its coverage into areas such as digital cellular phones, the numerous emerging standards for personal communication systems (mostly wireless), and wired and wireless networks including ISDN, SONET, ATM, and the Internet, along with discussions of the context in which they fit, and strengths and weaknesses.
