Abstract(in English) | This paper proposes analytical approaches for synthesis of the minimum L_2-sensitivity realization, one of the high accuracy digital filter structures. First, we prove that the minimum L_2-sensitivity realization of a second-order digital filter can be synthesized analytically by solving a fourth-degree polynomial equation of constant coefficients. Next, we show that the minimum L_2-sensitivity realization of an Nth-order digital filter can be synthesized analytically if its all second-order modes are equal. Furthermore, we derive a general expression of the transfer functions of Nth-order digital filters with all second-order modes equal. We show that the general expression is obtained by a frequency transformation on a first-order prototype FIR digital filter. |
