一、引言这篇文章回顾了稳态或瞬态随机数据(例如随机振动或声学数据)包括经过物理系统输入——输出关系的动态数据特性分析的定义与频域处理。介绍这些定义、专门符号与详细的计算方法是为了促使各不相同的用户的共同承认。
I. INTRODUCTION This article reviews the definition and frequency domain processing of dynamic data characterization including steady-state or transient random data (such as random vibration or acoustic data) including the input-output relationships of physical systems. Introducing these definitions, specialized symbols, and detailed calculations is intended to promote the common recognition of disparate users.
