| 摘 要： | 给出了一种基于巴特沃斯逼近的递归互补数字滤波器的设计方法，得到了由基本的全通节级联、并联构成的滤波器函数。结果表明，这种实现结构具有通带灵敏度低、系数少的优点。特别是当滤波器具有镜象对称的幅度频响时，实现滤波器所需的乘法极少。

| Abstract: | Butterworth-approximation based design method for recursive complementary digital filters is presented, giving the filter function implemented by a cascade-parallel connection of component all-pass sections. It is shown that this realization structure enjoys low pass-band sensitivity and fewer coefficients. Particularly, when a filter possesses a quadrature mirror magnitude response, the required multiplications for its realization are extremely fewer. |
