Introduction To Filters

This article will be limited to analog filters built with discrete components. Filters can also be made using digital signal processing (DSP) and analog distributed components (transmission lines and resonant cavities).


Data Processing Using SCAM - Part 2

In this article, I describe in detail how the SCAM (Super Content-Addressable Memory) manipulates queries against simple and complex data types. The data is assumed to be stored in a database. This should demonstrate to application programmers and database administrators how the SCAM enhances data manipulation performance compared to traditional computer configurations.

The Atari 2600
Remember the 1970s? Vietnam, Watergate, stagflation, polyester, bellbottoms, John Denver, gas rationing, Saturday Night Fever, and other events that made that decade, at least in retrospect, seem like 10 disheartening, frustrating years. But a few lasting bright spots emerged, as well. The personal computer was one of them.

Q&A
In this column, I answer questions about all aspects of electronics, including computer hardware, software, circuits, electronic theory, troubleshooting, and anything else of interest to the hobbyist.

Human Nature - Part 1
In my column, I often refer to human nature. I think it’s time to take a closer look at what actually constitutes human nature. This is important because engineers, as a group, are generally more interested in things than people. However, dealing with people in both personal and business settings is essential.

Near Space

The Well-Dressed Astronaut
Today’s Space Shuttle spacesuit doesn’t make a good spacesuit for planetary exploration because of the differences between working in weightlessness for a single mission and working on a dusty, gritty planet with gravity for months on end.

The Zilog Z8Encore! XP Microcontroller
A few months ago, I received an email from .(JavaScript must be enabled to view this email address) announcing a special offer of only $9.95 for their new Z8 Encore! XP 4K Series Development Kit. Like any good (or helpless) electronics shopper, I cannot resist a bargain like that, and promptly ordered a few kits to play with (one for me and a couple for my teaching colleagues).
