21. Intermodulation in loudspeaker drivers is, as with harmonic distortion , almost always larger than in most electronics. 22. Such harmonically related distortion is called harmonic distortion . 23. It is described by the company as " the finest harmonic distortion -sustain device developed to date ". 24. These amplifiers used a complex feed-forward servo system which resulted in very low 2nd order harmonic distortion . 25. This also minimizes the Total Harmonic Distortion ( THD ) within the amplifier down to 0.08 %. 26. At the end of the year, Jason Hughes also released an album with the band Third Harmonic Distortion . 27. X-parameters are also referred to as the parameters of the Poly-Harmonic Distortion ( PHD ) nonlinear behavioral model. 28. :: One might also consider frequency harmonic distortion or intermodulation noise if the input is a complex spectrum. 29. Other forms of inaccuracy include signal distortion ( frequently harmonic distortion of the sine / cosine signals ). 30. Non-power-factor-corrected SMPSs also cause harmonic distortion .
