Cancellation of nonlinear Distortion

  • Linear and nonlinear distortions are reduced
  • Constant transducer behavior over lifetime
  • Based on a nonlinear physical speaker model
  • Improved sound quality
  • Enhanced echo and noise cancellation

Nonlinear and time-variant transducer parameters will cause nonlinear and linear distortion in the transducer’s output signal. KCS uses a nonlinear filter structure, which is a mirror image of the determined transducer model.
The harmonic and intermodulation distortions synthesized in the mirror filter are subtracted from the input signal before it is fed to the transducer. Thus, the distortions generated by the transducer are compensated, and a linear relationship between the input signal and sound pressure output is established.


Demo Video

KLIPPEL Controlled Sound - Distortion Compensation - Technical Stimulus

In this video a technical stimulus signal consisting of a 22Hz and a 440 Hz sine tone signal is applied to the transducer. 
As shown in the first part of the demonstration the nonlinear transducer generates significant harmonic and intermodulation distortion. In the second part, KCS九游棋牌 is used to significantly reduce the distortion in the output signal.

 

 

 

KLIPPEL Controlled Sound - Distortion Compensation - Music Stimulus

KCS can reduce the nonlinear distortion produced by the transducer for any arbitrary music. The video demonstrates the audible effect of the distortion compensation on using such a music stimulus.
