| Abstract(in English) | In this paper, we compare the efficiency of compensating nonlinear distortions in electrodynamic loudspeaker system using two different types of Mirror filter, which called 2nd- and 3rd-order nonlinear IIR filter. These filters need nonlinear parameters of loudspeaker systems and we used estimated nonlinear parameters for evaluating the efficiency of compensating nonlinear distortions of these niters. Therefore, these evaluation results include the effect of the parameter estimation method. In this paper, we measure the nonlinear parameters using Klippel's measurement equipment and evaluate the compensation amount of both filters. Experimental results demonstrate that the 3rd-order nonlinear IIR filter can realize a reduction by 2dB more than the 2nd-order nonlinear IIR filter on nonlinear distortions at high frequencies. |
