Bob Fine

Building a High-Performance DSP System

Bob introduces Analog Devices' new ADSP-2100 family. After reviewing architectural characteristics, he uses a FIR-filter system design to demonstrate how easy it is to get a DSP up and running.

Brian McLeod

Real-Time DSP Modems with a PC and Sound Card

We've found yet another use for that sound card hidden deep inside your PC. This time, Brian and Matt explore real-time DSP-based V.22 QPSK and V.22bis modem demodulators using C++.



Frank Gao

Algorithms and Software for V.34 Modems

Software modems are more flexible and cost-effective than nonprogrammable chips. Frank shows us the operational principles and software building blocks of fax/modems so we can take advantage of this edge.


Brian Senese

Empowered Digital Filtering

Due to the memory and processing power restrictions within an embedded system, it is even more important to pick the best filter for the job. Brian provides insight into which filter to pick for specific applications.

Kenneth Baker

Self-Tuning PD Algorithm for the 68HC11

The day-to-day changes in power and mechanical loads gets controllers out of tune. Ken shows us the math and algorithms behind a self-tuning controller that knows how to maintain efficiency.



David Rector

Getting Started with Xilinx EPLDs

Part 3: Hands-On Project -- Implementation

In Part 1, we learned the benefits of designing with EPLDs. In Part 2, a timer/counter circuit was connected to an EPLD. Here, David demonstrates how the EPLD removes the guesswork from your logic designs.


Daniel Nygren

The Thrifty Engineer

Although Dan's not a lover of the embedded PC, he finds an ideal solution for one here. If you too have been unable to junk that old AT, perhaps you need to join Dan in a lesson on effective recycling.



Jeff Bachiochi

From the Bench

Tools: Part 1: Schematic Capture -- the Proverbial Electronic Napkin

Schematic capture programs have three main components -- the parts library, drawing editor, and postprocessor. Jeff shows us how to use these to guestimate cost and guide the PCB layout artist.


Tom Cantrell

Silicon Update

Flash Fight Flares

When it comes to flash, Intel and SanDisk are warmed up and in the ring. The big question: what factors will decide this match -- speed, weight, size, techniques, trainers, fan support... Where will you place your bet?
