The Copper Wire Gauge for Electrical Technology

An explanation of the A WG wire gauge system, with some handy tricks for converting between gauge and size. Insulated copper wire is used extensively in electrical and electronics applications. In amateur radio use, it is predominant. Copper is a metal with excellent thermal, electrical, mechanical and physical characteristics unequaled in its cost-benefit properties. Hence its widespread use throughout the world of electrotech-nology. Most amateur radio circuits use insulated...

ARRL Periodical CDROM to the rescue

You know QSTand other ARRL periodicals are invaluable resource tools. You hoard your back issues and refer to them over and over again. You panic because someone straightened up and now you're missing issues. Or even worse, your collection takes up so much room, your family has given THE ultimatum Either the magazines go or they do. But the worst part is that you still can't remember which elusive issue had that juicy project or the essential information you need right now If you've got a...

Complete DSP Design Example Using FIR Filters

Following this example through from start to finish will give you a good introduction to the process of designing a DSP application. The purpose of this article is to illustrate a design example for a digital signal processing DSP algorithm, from basic conception through real-time implementation. The algorithm chosen for illustration is the finite impulse response FIR filter. This class of digital filter is capable of excellent performance in amateur-radio applications, is fairly easy to...
