A concise introduction to the evolution of communication media, past, present, and future, this book is unique in that it treats both mass media—radio, television, and print—and interpersonal media—telephony, computer communication, and new technologies. The first part of The Evolution of Media describes the history and development of media technology. The second and third parts of the book develop a taxonomy for media and compare their technological requirements, applications, and other significant elements. The fourth part presents a simple methodology to help predict the success of new media products and services, using sample analyses to illustrate the process. The Evolution of Media is a useful supplement for foundational courses in mass communication and communication history, as well as a primer for anyone interested in understanding the big picture of communication media.

This easy-to-understand explanation of major aspects of today's telecommunications systems aims to give readers comprehensive coverage of the four major areas of telephone systems - station apparatus, transmission, switching and signalling. While maintaining all the fundamental information from the earlier editions, this revised and updated edition includes a perspective on telephony that includes central office, local loop, subscriber loop carrier, switching, multiplexing, LATA, signalling and network architecture. It also includes developments in fibre optic systems, information on PCS systems including GSM, TDMA, CDMA and policy implications of the US Telecommunications Act of 1996.

This work is intended for non-engineering industry professionals, students and anyone interested in learning the fundamental physical principles underlying the design of communications, devices and systems. This edition covers all the basic technological concepts of the principles behind modern communications systems. Beginning with first principles, it introduces the fundamental electrical and electronic definitions, and then builds upon them logically to cover more complex telecommunications concepts and computer-based systems. CD-ROM, quadrature amplitude modulation, and spread spectrum techniques used in current wireless technology, are covered in this edition.
