Electronic Design UPDATE edited by Richard Gawel, Managing Editor
With multi-gigabit rates traversing widely used FR4 pc-board backplanes, you can expect significant attenuation and distortion of the signal—not to mention the occasional surprise. Techniques such as pre-emphasis and de-emphasis as well as various forms of equalization have been developed to offset the signal degradation over the link. But how do you know beforehand what's needed, what will work, and in what combination? With Tektronix's Serial Data Link Analysis (SDLA) software, you can measure, predict, and test various solutions to optimize and finalize your design...

Join Electronic Design in the first of a series of Hotspot Webinars: Exploring How Good GUIs Drive Adoption in the Digital Power Management Space
A good GUI can help engineers design power systems for IT applications. The Webcast, scheduled for Wednesday, October 24 at 2:00 pm ET / 11:00 am PT and presented by Primarion, will examine real-world design situations and how a good GUI not only makes programming POLs more intuitive, it also organizes your thinking so important details aren't overlooked.

Direct broadcast video (DVB), DirecTV, Dish Network DBS, and very small aperture terminal (VSAT) satellite applications continue to grow, creating a need for a high-performance receiver. Maxim Integrated Products' MAX2112 direct-conversion receiver comes complete with mixers, a synthesized local oscillator, filters, and related support circuits on a single chip.

- Big companies use their resources to push little companies around unfairly.
- Little companies use loopholes to file unmerited lawsuits.
- It's too difficult to go after foreign companies that violate patents.
- Aside from some minor problems, the system is fine and doesn't need fixing.
More technical Content. More exhibits. More teardowns. More of what you need to know to find the right technologies, products and components to integrate into an ever-evolving array of complex applications. From Oct. 30 to Nov. 1, the Power Electronics Technology Exhibition & Conference, held in the Hilton Anatole hotel in Dallas, Texas, will give you the tools to optimize every element of the design process:
- An educational program focuses on practical, day-to-day solutions;
- A full contingent of suppliers demonstrating their latest innovations in the Exhibit Hall;
- And a conference schedule that hits all of the high notes - digital and portable power, power design, conversion and management, magnetics, alternative energy, LED drivers and more.

As a special thank you we will be doing a random drawing of participants, giving away Electronic Design T-shirts to 10 winners. Click here for the survey... |
National Instruments' LabVIEW is more than 20 years old, but most programmers have not had the benefit of using it. There are many UML (Unified Modeling Language) programmers, but most tend to deal with text-based programming languages, with C and Visual Basic at the top of the heap.
