| In most cases, connecting peripherals to a PC is not a problem. The fact that a USB stick, for example, has the same ground potential as a l...
| Connecting peripherals like USB sticks to a PC is usually straightforward since they share the same ground potential. However, USB-connected...
| The available range of opamps is vast. After selecting based on technical specs, further testing may be needed. Try this do-it-yourself opam...
| When measuring distortion in audio devices, it makes sense to filter out the controlling sinusoidal signal before the spectrum analyzer. Thi...
| Audio measuring devices usually have an input level range in which they work optimally and generate only little harmonic distortion themselv...
| The first article in this series presented a simple passive attenuator whose stages can be set using a jumper. Such a solution is well-suite...
