研究了一类有限有理函数的双线性变换对有限脉冲响应（FIR）数字滤波器的逼近。参考有理函数构造了最大平面选择滤波器和正交滤波器。所提出的方法可以直接用于偶数和奇数次滤波器，并产生简单的显式滤波器系数表达式。
The approximation of the finite-impulse-response (FIR) digital filters using the bilinear transformation of a restricted class of the rational functions is considered. The reference rational functions are constructed for maximally flat selective and quadrature filters. The proposed method can be directly used for both even and odd degree filters, and yields simple explicit expressions for the filter coefficients.
