It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

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 ...

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 ...

This application note presents a total harmonic distortion (THD) test circuit that uses active noise amplification to eliminate the need for expensive and often ineffective external filters. Abstract: ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...
