Understanding Telephone Electronics

Informationen zum Autor Joe Carr devoted his life to furthering a wider understanding of electronics and spreading his passion for radio, becoming one of the USA's best known technical authors with over 25 books and hundreds of magazine articles to his name. Newnes is proud to have published a number of his recent titles, including his last book, RF Components and Circuits. Steve Winder specializes in designing circuits for telecommunications applications, but has experience in a number of fields. As the current European Applications Engineer for Supertex Inc. Steve works alongside design engineers throughout Europe to design circuits using components made by Supertex, a U.S. based manufacturer of high voltage MOSFETs, CMOS integrated circuits and ASICs. Prior to joining Supertex, Steve was for many years a team leader for a group of analogue and digital design engineers at British Telecom's research and development laboratories, now known as Adastral Park, based near Ipswich, UK. Here, Steve applied his analytical skills to many technical areas but specialized in wideband analogue and digital transmission systems using copper pairs and optical fibre. In this role, Steve's strength was in radio frequency design, low-power design, low-noise design and systems engineering. Klappentext "Understanding Telephone Electronics" covers conventional telephone fundamentals including both analog and modern digital communications techniques. This fourth edition features new chapters on fiber optic technology and the Internet and Telephony. 5 photos. 200 figures.Covers conventional telephone fundamentals, including both analog and modern digital communication techniques. This book provides basic information on the functions of each telephone system component, how electronic circuits generate dial tones, and how digital transmission techniques work. It is suitable for technicians, engineers and students.
