8 Harv Weiner	New Product News HOT Works Configurable Processor from Virtual Computer Corp. SX Series microcontroller from Scenix Semiconductor, Inc. LP3100 C-programmable controller from Z-World T8ADH data acquisition card from Point Six, Inc.
12 Bob Perrin	, HTML, HTML Practical Analog Design Time for a refresher on op-amps? If so, here's the article for you. Bob covers op-amps from the basics of common op-amp configurations and modeling to the more advanced aspects of instrumentation amplifiers and complex circuit designs.
26 Mike Zerkus	HTML, HTML Antialiasing Techniques To get rid of aliasing in an ADC system, you can use linear active filters, switched-capacitor filters, ... You also better know when a filter isn't the answer. So, check out Mike's hints for anticipating as well as solving aliasing problems.
34 Tom Anderson	Selecting Position Transducers Are you choosing a position sensor or transducer but aren't sure how to weigh your options? Check Tom's parameter list. Prioritizing movement, environment, and contact requirements enables you to make the best decision.
Embedded PC 41 Harv Weiner	Nouveau PC Complete Scalable CPU from The parvus Corp. Voyager Software Development Kit from QNX Software Systems, Ltd. WinWedge 32 Pro from TAL Technologies, Inc. PCM-3820 PC/104 Flash Module from VersaLogic Corp. ADAM-4500 PC-based Controller from Advantech America
Embedded PC 46 Ingo Cyliax	Real-Time PC Graphical User Interfaces in RTOSs We can interface with an embedded PC via the Web, but how about a view that doesn't depend on HTML? And, what counts as real time for GUIs, anyway? Ingo has the answers as he gives us a close-up look at X Windows and QNX's Photon.
Embedded PC 54 Fred Eady	Applied PCs A New View, Part 1: Virtual Instrumentation Got a budget limit on test instruments for those one-of-a-kind gadgets? Well, don't spend your money. Instead, do what Fred does -- generate virtual test equipment using National Instruments' LabVIEW.
60 Don Lancaster	PostScript Flutterwumpers Pick a Peck of PostScript PICs The sound of "flutterwumpers" brings on a sort of Alice in Wonderland enchantment that's not unlike the peculiar magic Don Lancaster pulls out of PostScript. Listen in on how to make PostScript move PIC-powered robots.
65	Advertiser's Index
66 Joe DiBartolomeo	MicroSeries EMI Gone Technical, Part 4: Transient-Suppression Design Technique To tie together all his ideas on protecting against EMI and transient threats, Joe presents the protocol he uses when designing for transient protection. These general guidelines help you stop EMI from sneaking through.
72 Jeff Bachiochi	From the Bench Rebirth of the Z8, Part 2: Let Your Micro Answer All Want to see the future? Jeff's project merges a piece of the past (remember your old Magic 8-ball?) with Zilog's new OTP processors. It's crystal clear how easy it is to implement one of these new Z8s. Download: FTB94.ZIP
78 Tom Cantrell	Silicon Update FPGA Tool Time It's find to have a low-cost FPGA, but if the tools cost a mint, you're still in trouble. However, Tom's found some bargain basement tools just as far away as your local Internet connection.
