A video that explains the meaning of THD and how it's measured (plus any related theory) would be great. I believe you mentioned the term when discussing the uCurrent.
Hi
Just to be sure we're talking about the same thing:
THD = Total Harmonic Distortion
To measure:
Put in a sine wave at some frequency.
Get out a signal, it will have the sine wave plus harmonics due to distortion.
Measure just the harmonics.
Measure just the sine wave out.
Take the ratio of the harmonics to the sine wave out as a percentage and you have the THD.
Given the massive re-use of simple three letter abbreviations, it's sort of important to check that the sought after measure relates to something else...
