| Abstract(in English) | In this report, we propose a design method of FIR digital filters obtaining qausi-equiripple characteristic even if some notch frequencies change. A change in filter coefficients which depends on a change in notch frequencies is approximated by the polynomials using some variable parameters. In this method, the minimization problem for the polynomial coefficients with variable notches are formulated as semidefinite programming (SDP) in the frequency domain. However, the polynomial coefficients increase when variable parameters are the plural number. Therefore, we propose a reduction method of the polynomial coefficients. The values of term of high order in the polynomials are very small when variable parameters are the plural number and the polynomial orders are high order. As a result, the polynomial coefficients are able to reduce. Moreover we propose the suitable structure for the real time signal processing. We show effectiveness of the proposed method through an example. |
