| Abstract(in English) | A cascaded second order adaptive notch filters implemented using an allpass filter, for the elimination of multiple sinusoids, have been proposed. However, it has a problem that the convergence speed and estimation accuracy deteriorate when the angular frequencies of the multiple sinusoids are quite close to each other. Various adaptive algorithms for the adaptive notch filters are used. As one of them, a subband adaptive notch filters have been proposed. This is made up of the fullband and subband stages.The notch filter of the fullband stage is used to execute the elimination of the multiple sinusoids, whereas the adaptive notch filters in the subband stage estimate their angular frequencies. Therefore this method shows better convergence behavior compared with conventional one. Finally, computer simulation results are presented to confirm the convergence characteristics. |
