Publisher's Synopsis
Telecommunication is passing through an exciting stage of development which is likely to have a significant social impact. Recent advances have meant that even conventional telephone communication is now being implemented using digital transmission and switching techniques. The convergence of this digital communication technology with the wide-spread use of personal computers leads to an enormous potentiality for highly sophisticated communication facilities. Many of the older traditional modes of communication are now fading into obselescence, though much of the present network is likely to remain in use for some years.;This book bridges the gap between traditional telephony and that of modern digital communications technology. Greater emphasis has been placed on digital transmission and networks, with rather less on the fast-disappearing analogue network. Taking both into account, the text has been proportioned to reflect the significance of each in current practice. The author provides a broad introduction, both for those currently studying the subject of telecommunications as a specialist option and for those seeking to broaden or up-date their current knowledge.;Certain parts of the text relating to data transmission, especially those dealing with equalization and line coding, are based on original work forming part of the author's own research. The book also gives a brief introduction to cellular radio. In dealing with such specialized areas as pulse code modulation, optical fibre transmission and microwave links and satellite communication, the author provides a reference for those already qualified in engineering who may be wishing to change disciplines into a rapidly-expanding area of modern technology. The chapters on data transmission and data networks will also be of interest to those concerned with computer communications and networks.
