8 Harv Weiner	New Product News
12 David Prutchi	Digital Generation of High-Frequency Waveforms Cookbook waveforms from a function generator don't always provide the signals you need for testing. David shows how a numerical array and a DAC can yield nonstandard waveforms with arbitrary complexity. Download: DIGIVFO.ZIP
22 William Hohl Joe Circello	Frequency Domain Analysis with ColdFire Want a DSP and a microcontroller in the same chip? Listen in to hear how ColdFire's processor core, its multiply-accumulate engine, and signal transforms work together to provide cost-effective DSP functionality.
30 David Tweed	DSP-Based Canadian Timecode Receiver Part 2: Application Considerations Having conquered the theory of DSP transforms last month, David moves on to a practical application -- getting his local timebase to receive and adjust its clock to match that of CHU, a Canadian radio station.
Embedded PC 38 Harv Weiner	Nouveau PC
Embedded PC 43 Chip Freitag	A Stand-Alone Embedded Ethernet Platform Adding Ethernet to an embedded design gives you control via the Internet. Chip brings together an embedded Ethernet platform and an Am186. He gives guidelines for layout, chip clocking, data storage, as well as software concerns.
Embedded PC 48 David L. Feldman	A Formula for Winning Product-Development Strategies Sometimes, even when opportunity stares us in the face, it's difficult to get started. David gives us all a jump start by guiding us through a design process that makes sense for INK's Embedded PC Design Contest and the day-to-day job.
Embedded PC 53 Mike Justice Phil Marshall	PC/104 Quarter Industrial I/O Networks Although the desktop world essentially adheres to one network standard, the variation in industrial applications has led to the development of several networks. Mike and Phil suggest how to determine which standard you need.
Embedded PC 58 Fred Eady	Applied PCs Internet Appliance Development, Part 1: From the GUI Up And you thought you were unique? Nah! Even the embedded world wants to get on the Internet. Fred shows us some new tools that make it easier for companies to upgrade their clients' products remotely via the Internet.

66 Jan Axelson	MicroSeries Using Serial EEPROMs, Part 1: General Principles In need of nonvolatile, read/write memory? Perhaps, you should check out Jan's review of EEPROMs. She'll help you determine whether Microwire, SPI, or I2C is the solution.
74 Jeff Bachiochi	From the Bench It Can't Be a Robot, Part 2: It Doesn't Talk Jeff takes an RF transmitter/receiver and sticks it on the robot he introduced last month. But, to get his robot talking, he first has to filter out the idle noise, deal with preamble data, and solve the problems of one-way communications.
80 Tom Cantrell	Silicon Update Cruise the Funchips Often, Tom toys with the latest monoliths, and he's hard-pressed to get all the gory details down before the real-estate runs out. Today, he looks at a box full of gadgets that take care of time, temperature, and voice.
96 Steve Ciarcia	HTML Priority Interrupt Don't Lose Your Head
