| The American company QuantAsylum offers a range of affordable semi-professional audio analyzer tools and instruments. We tried out the QA403...
| The detection of low-level signal distortions places great demands not only on the dynamic range and linearity of the measuring device, but...
| Anyone who knows (or at least knows where to find) the formulae for designing analog filters will always be able to do the necessary calcula...
| When measuring the key characteristics of an audio circuit, for some parameters it is very desirable to remove the test signal from the circ...
| 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...
