Cover Story
- Voice over packet: putting it all together
Building a voice-over-packet system used to be a complex process of integrating several components and perhaps designing one or two of them yourself. Today
Design Features
- The nuts and bolts of signal-integrity analysis
Analyzing signal integrity is not like gazing into a crystal ball or shaking bones over a design to determine its viability. You must implement a set of tools, software, and reporting mechanisms to determine whether a design is acceptable to ship. - Solving the loop-analysis puzzle
Analyze PLLs, switch-capacitor filters, and other circuits with this simulation method, which yields regular loop measurements, such as gain and phase margins, directly from the transient simulation of the original discontinuous system.

How It Works
- Optical link forgoes constricting fiber, finds bliss in free space
Point-to-point optical links with 1-Gbps data rates serve many purposes.
Tech Trends
- Low-cost programmable logic: How low should you go?
Low-cost PLDs and FPGAs may give you the best bang for the buck, or they may be more hassle than they
