| Abstract(in English) | In this paper, we present the effectiveness of eliminating nonlinear distortions of loudspeaker systems for high sampling audio using Volterra filter. We have presented some identification methods and some compensation methods of nonlinear distortion of loudspeaker systems for audio, desktop and mobile phones. By using these compensation methods, the nonlinear distortion of loudspeaker systems for high sampling audio can be compensated. In this paper, we aim at the nonlinear distortion produced by multi-sinusoidal waves on unaudible frequency band. We therefore present the effectiveness of eliminating nonlinear distortions of loudspeaker systems for high sampling audio through some experiments of eliminating the 2nd-order nonlinear distortions. Experimental results show that the levels of the 2nd-order nonlinear distortions can be reduced in the range of 5[dB] to 15[dB] compared with before elimination over the whole frequency band. |
