本文提出了一种综合（可能）非对称双频或多带滤波器的新方法。后者概括了经典的切比雪夫合成，它计算的最大-最小优化问题的最优解，通常的低通原型的滤波功能。该方法的计算部分由Remez型交换算法组成。作为一个例子，考虑根据SPOT 5航天器的非对称规范设计双频带滤波器，并产生一个7度滤波器，该滤波器有利地取代了由2个独立滤波器通过输入端的波导结“双工”制成的通常解决方案/输出端口
In this paper, a new method for the synthesis of (possibly) asymmetric dual-band or multi-band filters is presented. The latter generalizes the classical Chebyshev synthesis in that it computes the optimal solution of a max-min optimization problem specified in terms of the filtering function of the usual low-pass prototype. The computational part of the method consists of a Remez type exchange algorithm. As an example the design of a dual-band filter from asymmetric specifications for the SPOT5 spacecraft is considered, and yields a 7th degree filter that replaces advantageously the usual solution made out of 2 separate filters "diplexed" by means of waveguide junctions at their input/output ports
