[Technology Report]
All-Digital Approach Hikes Audio Quality In Consumer Products
From professional studios to car radios to home entertainment systems, the demand for high-quality audio is on the rise. The increasing performance of low-cost programmable DSPs is helping makers of these systems meet customer demand. In... — Ashok Bindra

[Product Innovation]
Chip Set Creates High-Speed, Fail-Safe Switch Fabrics
As more data moves around and between various networks, data-switching speeds need to increase. But higher speed isn't the only requirement because networks now carry audio, video, and other time-dependent information. So, quality of service (QoS)... — Dave Bursky

[Design Application]
Key Considerations For ESD Circuit Protection
Circuit designers face many electrostatic-discharge (ESD) concerns in their quest for a functional and reliable product. Moreover, the evolution of the electronics marketplace toward higher data throughput and faster signal speeds adds to this... — Contributing Author

[Ideas For Design]
Transformer Improves High-Pass Filter Performance
The low-frequency LC performance of a high-pass filter is strongly affected by the quality of the filter components. Typically, the inductor is the component that deviates most significantly from the ideal. The first-order inductor... — Contributing Author

[Ideas For Design]
Eight-Wire Resistive-Touchscreen Controller Has I²C Interface
An analog, resistive touchscreen is a sensor consisting of two opposing layers, each coated with a transparent resistive material. The layers are separated by small spacer dots of nonconductive polyester that prevent the two layers from making... — Contributing Author

[Editorial]
Power Conservation: Are We Just Squeaking By?
Earlier this year, I raised the issue of energy conservation and what consumers and the industry could do to reduce energy consumption. California and a number of other states faced considerable energy shortages this summer, due to a combination of... — Dave Bursky

What's All This ROI Stuff, Anyhow? (Part 2)
I'm sitting here typing at 11 p.m. by the light of a 100-W incandescent bulb. Not a fluorescent? No, not a fluorescent bulb. Why not? Because I am definitely willing to pay a penny per hour for good quality of light to make my job easier and... — Bob Pease

[Viewpoint]
OEMs Will Benefit From Royalty-Free Real-Time Operating Systems
The convergence of wireless com-munications and the Internet in business and consumer products, like Internet-enabled phones, personal digital assistants (PDAs), PCs, and other handheld consumer devices, is creating increased demand for embedded... — Contributing Author

[Editor's Notebook]
Beware Of Pretty Punctuation Marks Bearing Gifts
Buyer beware is good advice, especially where cell phones and software are concerned. It started so innocently: my cellular phone vendor, whose logo looks like a cute asterisk, called and offered me a free phone. I would just have to renew my... — William Wong

Bad Drives Out The Good
Heard of Gresham's Law? It says that "bad money drives out the good." This applies to more arenas than finance, like management. Bad managers drive out the good ones. Once there's a tipping balance—enough bad managers to make a fatal... — Ray Weiss
