[ED Bookstore] RF Measurements For Cellular Phones And Wireless Data Systems
The title accurately tells what this book is about, but there is so much content here I do not know where to start. Essentially the book is about how to test and measure the wide range of wireless gear now being developed with an emphasis on cellular equipment. It is pretty rare to find a book on this subject and especially one that is reasonably up to date. Well, I’ve found one.

[Technology In The News] Looking For An Open-Source ECG
The electrocardiogram (ECG) is a very important diagnostic tool for heart health. But as common as it is in the U.S. and other developed countries, the ECG is still expensive enough to be unaffordable to doctors in many third world countries.

December 11, 2008[Engineering Feature] Controlling The Home
Multimedia is already part of home-automation systems. Take, for instance, Control4’s range of products from lighting and climate control to switched audio. Wallmount LCD panels provide a convenient portal to an array of controllable options within the home (see the figure). Home-automation system installers typically handle this class of product. In the past, these systems were...

December 11, 2008[Engineering Feature] The Real Universal Remote
One common element between home-automation and media systems are control points. These may be panels, radio or infrared remotes, and PCs. They could also be cell phones, wireless phones, or MP3 players. Unfortunately, the universal remote doesn’t exist yet. Infrared TV remote controls are a start, but they can be a pain to program. They also need to be pointed at the appropriate device or an action will not be recognized. Moreover, this type of remote is...

December 11, 2008[Engineering Feature] Standalone Playback
Players without recording capability are also emerging. Western Digital’s WD TV, for example, uses an external USB 2.0 hard drive like Western Digital’s own My Passport or My Book products to store its audio and video files (see the figure). It only handles non-encrypted multimedia, but there’s plenty of that available. An external drive can upgrade and move data to different players....

December 11, 2008[Engineering Feature] The Connected Home Remains Stuck On Pause
Multimedia nirvana is coming to the home... hopefully sometime in our lifetime. A flood of HDTVs, set-top boxes, home-theater PCs, and universal remotes (I have six, by the way) has poured into the market, yet getting them to play together is a challenge even a geek would like to avoid. Nonetheless, the climate is improving. Next year, we’ll likely see a convergence around standards such as UPnP (Universal Plug and Play), DLNA (Digital Living Network...

December 11, 2008[EEPN In Electronic Design] USE GDTs For Surge Protection In Broadband Digital Comm
Gas discharge tubes (GDTs) have evolved to a level of providing very reliable and effective surge protection in telecommunications systems and equipment, safeguarding against lightning and power-fault conditions. Due to their robust nature and superior electrical characteristics, GDTs have already become the preferred replacement for carbon blocks in traditional telephone-service applications. Because of their ultra-low capacitance plus low insertion and ...

[Design View / Design Solution] The ABCs Of Fiber Bragg Gratings
As the demand for bandwidth and high-speed transport grows, so does the use of fiber-optic based transport. One of the enabling technologies associated with optical transport are Fiber Bragg gratings (FBGs). This tutorial will introduce the concept of FBGs and describe the advantages provided by use of FBGs for chromatic dispersion compensation.
