Second order Volterra inverses for compensation of loudspeaker nonlinearity

  title={Second order Volterra inverses for compensation of loudspeaker nonlinearity},
  author={Hans Schurer and Cornelis and Slump},
High quality sound reproduction by loudspeakers is increasingly problematic if the dimensions of the loudspeaker decrease. To produce enough power, large diaphragm excursions are needed which give rise to significant distortions especially at very low frequencies. Instead of improving the mechanical construction of the transducer we apply a feedforward nonlinear digital inverse circuit. Results of two 2nd order Volterra compensators show a significant reduction of the second order harmonics… CONTINUE READING
