当网络的传输零点为复数时,本文提出了一种新的综合方法。这种方法分两步进行:(1)采用类似Brune的方法,将网络展开成含负元件的梯形网络;(2)求出不含负元件的等效网络。文中提出并证明了梯形展开定理,分析了梯形展开时的一系列特性;随后给出了三种等效分网络(即三元件网络、无磁耦网络和Darlington D型网络),讨论了综合过程中所遇到的一系列问题。文末还举例说明了本方法的实际应用。
When the transmission zeros of the network are plural, this paper presents a new integrated method. This method is carried out in two steps: (1) Unfolding the network to a trapezoidal network with negative elements using a Brune-like approach; and (2) Calculating the equivalent network without negative elements. In this paper, the trapezoidal expansion theorem is proposed and proved, and a series of characteristics of trapezoidal expansion are analyzed. Then three equivalent sub-networks (ie, three-element network, non-magnetic coupling network and Darlington D network) are given. In a series of problems encountered. The article also illustrates the practical application of this method.
