Power Supplies for LED Driving, Second Edition explores the wide
use of light-emitting diodes due to their efficient use of power.
The applications for power LEDs include traffic lights, street
lamps, automotive lighting, architectural lights, theatre lighting,
household light replacements, signage lighting (replacing neon
strip lights and fluorescent tubes), LCD display backlighting, and
many more. Powering (driving) these LED's is not always simple.
Linear driving is inefficient and generates far too much heat. With
a switching supply, the main issues are EMI, efficiency, and of
course cost. This book covers the design trade-offs involved in LED
driving applications, from low-power, to UB-LEDs and beyond.
Despite the complexity of the subject, this wealth of information
is presented succinctly and in such a way, using tables, diagrams
and brief explanatory text, as to allow the user to locate
information quickly and easily. Thus the book should be invaluable
to those involved with the installation, commissioning and
maintenance of data communications equipment, as well as the end
user.
*A practical engineer's reference that puts the key information at
your fingertips
*Covers essential data, techniques and working practice
*This update covers the latest international regulations
Throughout its history, Understanding Telephone Electronics has
been, by far, one of the most popular books on telecommunication
electronics in the trade, electronic distribution, and educational
markets because of its very simple, direct approach to the
technology. In keeping with the distinguished tradition of its
predecessors, Understanding Telephone Electronics, Fourth Edition
covers conventional telephone fundamentals, including both analog
and modern digital communication techniques, and provides basic
information on the functions of each telephone system component,
how electronic circuits generate dial tones, and how the latest
digital transmission techniques work.
This new edition of Stephen Bigelow's well-known, widely used text
on telephone electronics offers comprehensive coverage of the
latest developments in fiber optic technology, the convergence of
telecommunications, cable-TV and Internet services, and CTI
(computer telephony integration). The authors have made extensive
revisions in these and other essential areas, such as business
systems, voice mail, phone networking, enhanced services, satellite
communications, wireless paging systems, digital communications,
and much more to ensure that topics covered are current with the
most recent advances in technology. The original Understanding
Telephone Electronics has been a "gold standard" reference and
training staple for years. Likewise, Understanding Telephone
Electronics, Fourth Edition will serve as an essential and
invaluable resource for technicians, engineers, students at major
universities and corporations, and anyone with an enthusiasm for
telecommunication electronics.
Provides comprehensive coverage of telephone system functions and
the role of the Internet in telephony
Updates encompass the trends and advances of the booming
telecommunications field, with new chapters on fiber optic
technology and the Internet
New material in the third edition includes mobile base station
antennas, operation of cellular networks, SAW filters and ceramic
resonators, modulation for stereo FM broadcasts, ADPCM, and
vocoders.
*The essential data and information for modern radio engineering at
your fingertips
*Based on the practical knowhow of practicing engineers
*Ideal for reference and revision
Newnes Telecommunications Pocket Book is a unique pocket reference
written by an engineer for engineers. The information in this book
covers the data, methods, standards and fundamentals needed in a
wide range of work situations. The practical focus of the book
makes it essential for all telecommunications professionals and
managers, and also for students who want to find the key
information quickly.
The scope of this book encompasses signal sources, radio
propagation and modulation, cabling, high speed data systems,
switching, LANs and WANs, multiplexing, and the whole range of
telecomms equipment: telephone systems, mobile phones, pagers,
modems, fax, private mobile radio...
Review of the previous edition
'There is something relevant to all practising telecommunications
engineers and the book will be particularly valuable to those
looking for a basic but sound appreciation of fields outside their
particular speciality. In short an excellent book.' BT Engineering
Journal
All sections have been thoroughly updated to cover the latest
developments in technology and standards, including ITU
regulations, WAP, GSM1800, HDSL2, wireless local loops and wireless
broadband, optical fibre amplifiers and the latest submarine cable
systems.

Light-emitting diodes are being widely used due to their efficient
use of power. The applications for power LEDs include traffic
lights, street lamps, automotive lighting, architectural lights,
household light replacements, signage lighting (replacing neon
strip lights and fluorescent tubes), and many more.
Powering (driving) these LED's is not always simple. Linear driving
is inefficient and generates far too much heat. With a switching
supply, the main issues are EMI and efficiency, and of course cost.
The problem is to get a design that meets legal requirements and is
efficient, while costing the least. This book covers the design
trade-offs involved in LED driving applications, from low-power to
UB-LEDs and beyond.
* Practical, "hands-on" approach to power supply design for LED
drivers;
* Detailed examples of what works and why, throughout the design
process;
* Commentary on how the calculated component value compares with
the actual value used, including a description of why the choice
was made.
Unlike most books on filters, Analog and Digital Filter Design does
not start from a position of mathematical complexity. It is written
to show readers how to design effective and working electronic
filters. The background information and equations from the first
edition have been moved into an appendix to allow easier flow of
the text while still providing the information for those who are
interested.
The addition of questions at the end of each chapter as well as
electronic simulation tools has allowed for a more practical,
user-friendly text.
*Provides a practical design guide to both analog and digital
electronic filters
*Includes electronic simulation tools
*Keeps heavy mathematics to a minimum
