本文提出了一种合成非对称多带滤波器的新方法。后者的主要改进在于，它不仅计算通常低通原型的滤波函数的最佳反射零点，而且还计算最佳透射零点。计算部分由类似微分校正的算法组成，该算法已被证明是收敛的，并且保证了响应的最优性。给出了实现这种算法的实用信息。该过程通过非对称规格的双带滤波器设计进行了验证，该滤波器产生了 9 度滤波器。
In this paper a new method for the synthesis of asymmetric multi-band filters is presented. The major improvement of the latter is that it not only computes optimal reflection zeros but also optimal transmission zeros of the filtering function of the usual low-pass prototype. The computational part consists of a differential correction-like algorithm proven to be convergent, and which guarantees the optimality of the response. Practical information is given for the implementation of such an algorithm. The process is validated by the design of a dual-band filter from asymmetric specifications, which yields a 9th degree filter.
