| Professional-grade equipment for characterizing and developing audio equipment is usually beyond the means of a hobbyist lab. However, it is...
| We recently put a neat thermal camera through its paces to test its usefulness in the lab. We found that this pocket-sized camera can quickl...
| When it comes to high-precision signal measurement, you must stick with time-proven techniques. This article describes how to measure distor...
| The third and final part of this series on the design of analogue filters deals with the subtleties of passive filters. Since only purely pa...
| In this second part in our series of articles on the design of analogue filters, we will look at active filters. The inductors that are used...
| This series of three articles deals with the design of analogue filters. The first part covers the basic theory with an emphasis on practica...
| Do you want to measure not only electrical signals but also optical signals? Then you need an optical probe that converts light intensity in...
| What’s this? A multimeter with a graphic display? That sounds interesting… The PeakTech 3440 can not only display measured values, but also...
| Upgrading the CPLD board: With an MAX10M08 CPLD as the core component, the board not only provides more logic elements than the previous ver...
