Cover Story
- Blindingly fast ADCs
To get meaningful information, not just "data," you need to know how your converter is looking at your signal.
Design Features
- Benchmarking DACs for communications requires a system-oriented
approach
DACs for modern communications systems are highly sophisticated. Selecting the right one for your application requires you to be sophisticated, too. A device that works in your prototype may or may not be right for the product you want to ship. - How to make residential phones regulate their own power.
As broadband access changes the architecture of telephone systems, central-office-regulated power for residential phones will go the way of the buggy whip. Fear not. - Ceramic capacitors in dc/dc-input filters: OK, but watch out for those
transients
Designers now have new reasons to use ceramic, rather than tantalum, capacitors. But be careful.

How It Works
- Is anyone talking?
Almost three million people are looking for signs of extraterrestrial intelligent life.
Tech Trends
- PCI keeps on ridin' high
PCI, the wildly successful I/O interconnect bus that virtually all desktop PCs and many embedded systems use, continues to transform itself to stay atop the growing technology wave.
