1-05-2023 | The detection of low-level signal distortions places great demands not only on the dynamic range and linearity of the measuring device, but...

1-11-2022 | 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...

1-09-2022 | When measuring the key characteristics of an audio circuit, for some parameters it is very desirable to remove the test signal from the circ...

1-07-2022 | Professional-grade equipment for characterizing and developing audio equipment is usually beyond the means of a hobbyist lab. However, it is...

1-05-2021 | 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...

1-05-2021 | When it comes to high-precision signal measurement, you must stick with time-proven techniques. This article describes how to measure distor...

1-01-2021 | 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...

1-11-2020 | 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...

1-11-2020 | Measuring the dynamic behaviour of a circuit without a differential current probe is very challenging. To tackle such challenges we present...

1-09-2020 | This series of three articles deals with the design of analogue filters. The first part covers the basic theory with an emphasis on practica...
