WebOur test signal consists of a series of 125 Hz sine tones that have deliberately been distorted. The first sine tone has a total harmonic distortion (THD) of 5%; it has been severely damaged. Listen to that file first, and then listen to the others, which have decreasing THD levels. WebAlso notice that the -3 db point in the filter’s knee is at 2.000 kHz. This would be unacceptable for THD testing as it’s starting to attenuate the second harmonic (2 kHz) of the 1 kHz fundamental and will display a test reading of that harmonic 3 db lower than what is really occurring at that point.
