| Abstract(in English) | The harmonic distortion level measurement technique of the loudspeaker by using the adaptive filter can be easily implemented even in a low performance DSP, because the computational complexity of this technique is much smaller than the conventional measurement technique by spectrum analysis. However, the convergence time of the adaptive filter disturbs the shortening of the measurement time. This paper describes that the harmonic distortion level measurement technique by using the adaptive filter can measure the accurate harmonic distortion level even if the convergence of the filter output signal is not complete yet, by estimating the fundamental frequency component and the harmonic frequency component at the same time. |
