摘要
利用算子将微分方程转换成系统函数,借助梅森公式对系统函数进行分解,提出一种画出分解后系统方框图的简单方法。该方法可应用于通信工程系统分析,在整体分析中起到辅助分析作用。利用系统方框图的分解将前向通道与反馈环路分别进行讨论,可以简化对复杂系统的直接分析,在一定程度上降低了系统分析的难度。通过数学分析证明了该方法的正确性。
A kind of method of drawing a system chart is introduced in this paper, by using the operator to transforming differential equation into a system function and by using Mason formula to decompose the system function. The method can be applied to the analysis of communication engineering system, and it plays an auxiliary role in the whole analysis. By using the decomposition of the block diagram of the system, the forward channel and the feedback loop are discussed respectively, which can simplify the direct analysis of complex systems, and reduce the difficulty of system analysis to a certain extent. The method is proved by mathematical analysis.
