| Abstract(in English) | In this paper, the structure and control algorithms of an infinite impulse response digital adaptive filter (IIR-ADF) for adaptively eliminating multiple sinusoidal components from the observed broadband signal is proposed. The IIR-ADF is composed of a number of second order IIR filters parallely connected, which one of those eliminates each sinusoidal component. In our proposed method, the poles of ADF are controlled by the estimated center frequency of the sinusoidal components obtained from the converged value of the FIR part's coefficients which give the zero position of the ADF. Since the pole radius of the IIR filter is always ensured to be smaller than one, hence the stability of the filter is guaranteed with small computational cost. The ADF is implemented by a DSP-chip to verify the expected characteristics, and the computational load in term of the number of machine cycle is also clarified. |
