| 摘 要： | 传输零点的确定是交叉耦合滤波器综合的最基本要素.本文利用广义Chebyshev函数的极值特性以及滤波器阶数与传输零点最大值的关系,提出了一种根据滤波器特性指标同时确定广义Chebyshev滤波器的阶数和传输零点位置的方法,弥补了传统方法中传输零点确定的人为随意性,在满足技术指标条件下,实现了广义Chebyshev滤波器阶数最少,传输零点位置最佳.几个数值实验显示了该方法的过程和有效性.

| Abstract: | Determination of transmission zeros is important in synthesis of cross-coupled filter.A novel method to determine the general Chebyshev filter degree and transmission zeros at the same time is proposed according to the extreme characteristic of the general Chebyshev function and the relationship between the filter degree and the number of transmission zeros. On the condition of the given filter specificafions, the least filter degree and the optimum positions of transmission zeros are realized. Several simulation examples illustrate the procedure and the validity in the filter design of the proposed method. |
