Designing total-harmonic-distortion (THD) measurement into a system usually involves a notch filter and a broadband ac measurement. The problem with this technique is that it measures both THD and ...

Measuring an op amp’s THD(total harmonic distortion) at frequenciesbelow 100 kHz is problematicbecause modern amplifiers have a THDrating that is much lower than that ofmost test equipment. The ...

A couple weeks ago I built a simple 1KHz 6Vpp Sine Wave Generator from a handful of opamps and passives I had laying around. You can check out that project here. I thought it would be fun to quantify ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

Chestnut Ridge, NY. Teledyne LeCroy has introduced a new harmonics calculation option for the MDA800 motor drive analyzer series. This optional software package enhances the standard capabilities of ...
