[Technology Report]
Logic And Protocol Analyzers Acquire More Muscle
For designers of telecommunications and wireless products, the challenge is to choose an appropriate mix of instruments for analysis and debug, and the move is to logic and protocol analyzers. Fledgling digital system designs are still plagued by...  — Stephen Grossman

[Product Innovation]
Speech Chip Listens Well, Talks Clearly, Plays Music
Low-cost high-quality speech recognition and synthesis has been the holy grail of the electronics industry for several decades. It's here now in the RSC-4x family of speech-recognition and synthesis chips from Sensory Inc. Each chip needs just an...  — Dave Bursky

[Design Application]
Successful IC Design Takes Front- And Back-End Teamwork
Today, the success or failure of an advanced IC design depends largely on how smoothly it traverses the design process. Greater cohesiveness between front- and back-end design domains is critical to the productive development of advanced ICs in this...  — John Gallagher

[Ideas For Design]
Circuit Monitors Pump On/Off Times To Ensure Safe Operation
In a septic-tank-based sewage system, waste water and toilet wastes from, say, a residence drain into the first compartment of a two-compartment septic tank. A grating between the compartments allows just liquid waste to drain into the second...  — Lawrence Arendt

[Ideas For Design]
Circuit Controls Two LEDs With One Microcontroller Port Pin
Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one port pin. This can be very useful when there are no...  — Spehro Pefhany

[Ideas For Design]
Simple Circuit Uses Optical Fiber To Send Relative-Humidity Data
The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal cables that...  — Shyam Sunder Tiwari

[Editorial]
Little Things Mean A Lot For Design Collaboration
Chip complexity has increased phenomenally, with gate counts pushing beyond 10 million. It takes the collaboration of a large team of creative talent to design one such complex chip or boards containing dozens of them. Often the necessary talent is...  — Dave Bursky

[Pease Porridge]
What's All This Ginger Stuff, Anyhow?
Most of you have seen the big splash about the "Segway," previously known as "Ginger," previously known as "It." It's a high-tech motorized scooter with two wheels that are—no kidding—side by side. Obviously, Ginger is a great technical...  — Bob Pease

[Editor's Notebook]
Will Li-Ions Eventually Rule The Automotive Battery Jungle?
Some experts predict that fuel cells will power the cars of the future. But with fuel-cell vehicles and infrastructure still early in their development, hybrid electric vehicles, or HEVs, are more likely to emerge as the auto industry's near-term...  — David G. Morrison
