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.

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.


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.

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.

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.

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.

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.

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.

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.


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.
