摘　　要：给出了一种随机信号通过线性系统相关函数之间相互关系的推导方法 .只需在系统图上找出一个相关函数的标示路径及其等效路径 。A simplified method was proposed to deduce the relationship between correlation and/or autocorrelation functions when stationary random signals go through linear shift invariant systems. The process is just to draw an equivalent route between the two parameters needed to be correlated and write down the formula by reference to the two rules presented in the paper.
