| Abstract(in English) | A design method of FIR and IIR fanfilter with a part of variable attenuation in the stopbands is proposed in this paper. In the case of FIR fanfilter, its characteristics can be changed by coefficients that are approximated by polynomial. In the case of IIR fanfilter, its characteristics can be changed by numerator and denominator coefficients that are approximated by polynomials. Both FIR and IIR fanfilter's optimization methodology is solved semidefinite programmings in a frequency domain. Then we get optimum coefficients by solving these optimization problems. Finally, design examples are given to demonstrate the proposed method. |
