在双口网络分析设计中,为了方便,常常根据实际情况选用某种参数表征网络特性。例如,一般用 A 参数描述链联双口网络特性,用 Z 参数描述串联双口网络特性,而在需要实际测量时,又采用实验参数描述等等。这样,在整个分析设计过程中,往往需要进行不同参数间的等效转换。一般说来,这种转换计算属于相量运算,用人工方式进行时,不仅计算繁复、精度低,而且很容易出错。此外,在研究接有电源和负载的双口网络特性时,其网络函数计算也有类似困难。应用微型计算机解决上述问题是很方便的。本文介绍一个用于双口网络特性参数转换及网络函数计算的计算机程序。根据网络理论,如图1所示双口网络的 Y 参数、E In the dual-port network analysis and design, for convenience, some parameters are usually selected according to the actual situation to characterize the network. For example, the A-parameter is generally used to describe the characteristics of a linked dual-port network, the Z parameter is used to describe the serial dual-port network characteristic, and the experimental parameters are used when actual measurement is needed. In this way, the entire analysis and design process, often need to be equivalent conversion between different parameters. In general, this conversion calculation belongs to the phasor calculation, when performed manually, not only complicated calculation, low accuracy, but also easy to make mistakes. In addition, there are similar difficulties in calculating network functions when studying the dual-port network with power and load. It is very convenient to use the microcomputer to solve the above problem. This article presents a computer program for the conversion of dual-port network characteristics and network functions. According to the network theory, as shown in Figure 1 dual-port network Y parameters, E
