摘要
本文将信息量等概念及最大熵的概率估计方法引入随机振动信号分析,给出随机振动的信息量及信息熵的概念,讨论了随机振动的信息描述.最后以复合振动信号为例,给出它的最大熵概率密度函数.
The concepts of information quantity and information entropy and the method of maximum entropy probability estimation are introduced to random vibration signal analysis in this paper. the description of information of random vibration is discussed. As an example, the maximum entropy probabilistic density function of a compound vibration signal is calculated.
