本文提出衰减特性和通带延时特性同时最佳逼近的通用参数滤波器的理论,推广了通常的通用参数滤波器(不具有象限对称复数衰减极点的滤波器)的理论,并在通带延时特性方面提出新的概念和方法,使同时最佳逼近得以完成。文中推导有一系列公式。在优化逼近过程和起始逼近等方面,文中也有完整的结果。利用本文所得结果来设计各类滤波器,其优越性已为我们在实际设备中的具体应用所证实。
In this paper, the theory of universal parametric filter, which has the best attenuation and passband delay characteristics, is proposed. The general general parametric filter (filter without quadrant symmetric complex decay pole) is generalized. New features and methods are proposed in the characteristics of time so that the best approximation can be accomplished at the same time. Derived a series of formulas. In the optimization of the approximation process and the initial approximation, the article also has complete results. Using the results obtained in this paper to design various types of filters, its superiority has been confirmed by our specific application in real equipment.
