Description

Loudspeaker system is modeled by the Volterra series expansion. We have proposed a method measuring the Volterrra kernel of the loudspeaker system by multi sine wave. However this method has a problem that doesn't consider third order distortion, and over. Therefore, we propose the new method measuring the second-order Volterra kernel by the multi sine wave. In this method, the third order distortion is considered. Furthermore, we propose the new automatic measuring system of second-order Volterra kernel considered third order distortion. And, we experiment on the elimination of the nonlinear distortion of loudspeaker system with the Volterra kernel measured by the new automatic measuring system on offline.
