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 ...

Since the test equipment was designed before switching amplifier systems were conceived, THD+N readings may easily be unreliable or misleading. In other words, in the world of switching amplifiers, ...

I googled a bit, but couldn't find any good apps that help assist in the testing of an audio device (like an MP3 player). I would like to test the THD and the SNR of the device. Are there any good ...
