ICCE reflects broad scope of user demands News & Analysis 6/15/2001 Post a comment With diverse digital consumer systems poised to hook up to myriad applications and services while simultaneously networking among themselves, the task of designing consumer electronics is getting more and more complicated.
VHDL-AMS simulation for battery chargers News & Analysis 6/13/2001 Post a comment How easy-or-difficult is it to create VHDL-AMS models for analog circuits. Electronic Engineering in the UK published this Mentor Graphics code listing for a Maxim NiCd battery charged. Take a look...
Linux: the ideal client/server link News & Analysis 6/8/2001 Post a comment Some of the most innovative and revolutionary results occur when methods from one field are combined with methods from another. Networked file systems, digital signal processing and graphical user interfaces combined with Internet-enabled hypertext are just three of many examples. A new juxtaposition is emerging that could be just as profound in its effects--combining the traditional embedded paradigm with the classical network-based client/server model.
New Web services need structure News & Analysis 6/8/2001 Post a comment No one can dispute that the Web has fundamentally altered the way we shop, do business and are entertained. But underneath it all, the Web remains what it has always been-an enormous collection of networks that offers a pervasive and accessible medium for content and services.
Standards ease Web-app designs News & Analysis 6/8/2001 Post a comment Despite the market slump and the highly publicized failure of many dot-com ventures, the stampede to establish a business presence on the Web continues.
Solution to Web-service chaos: frameworks News & Analysis 6/8/2001 Post a comment As the World Wide Web morphs under our fingertips, companies, engineers and developers are trying to determine the exact nature of an environment that embraces high bandwidths, new types of devices, increased connectivity, new languages and protocols, and ways of using the Web that did not exist even a year ago.
Germany's SZ Testsysteme moves into Japanese market News & Analysis 6/4/2001 Post a comment TOKYO -- In a move to expand its presence in Japan and Asia, SZ Testsysteme AG of Germany today opened a new subsidiary in the Tokyo suburb of Chiba.

A Quadrature Demodulator Tutorial Design How-To 6/4/2001 Post a comment Quadrature demodulators are important circuits for frequency modulation and certain digital-modulation applications. Motorola's Danielle Coffing and Eric Main offer a quadrature demodulator tutorial, complete with transfer-function derivation and IC implementation.
Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses?
