用Mason公式化简信号流图的计算机算法

通常在分析求解复杂网络参量或外特性参量时,都是求解线性代数方程组,或用拓扑分析法将线性方程组画成信号流图,利用 Mason 法则从图形上直接求出外特性参量。用手工方法进行这项工作比较麻烦。作者推出用计算机求解信号流图的计算方法,此法准确迅速,可求多至99个节点的复杂网络。

A COMPUTATIONAL METHOD OF USING MASON FORMULA TO SIMPLIFY THE SIGNAL FLOW GRAPH

When one analyses the complicated network pararmeters and characteris- itic parameters the linear algebraic equations are usually solved or exterrio characterisitic parameters are directly obtained from graph by means of trans forming the linear algebraic equations into a signal flow graph using topologic analysis method and Mason principle.But it is difficult to do these by hand. In this paper the authors derive the computational method of solving sigal flow graph by computer.This method can efficiently solve the complicated network with 99 nodes.
