自功率谱密度 meaning in Chinese
auto-spectral density
Examples
- In order to obtain these data , we must at first calculate apsds ( auto - power spectral density ) and cpsds ( cross - power spectral density ) of the three signals in the system
而想要得到这些核心参数,必须先分析估计出系统中三路信号的自功率谱密度和两两之间的互功率谱密度。 - Studies have been made on arithmetic realization of apsd estimate in a high - speed detect system , since the way of calculating cpsd is only a little different from that of calculating apsd
鉴于互功率谱密度估计算法只需将自功率谱密度估计算法中的自协方差函数换成互协方差函数,本文仅研究和讨论了自功率谱密度估计算法及其实现。 - In the first session the fans vibration on - line monitoring system is realized with vc language , also compile auto power spectrum density function , cross power spectrum density function , autocorrelation function and cross correlation function etc spectral analysis function to carry through simple offline fault diagnosis
首先用稳定性强、扩展性好的vc + +语言开发了通风机振动在线监测系统，并编写了自功率谱密度函数、互功率谱密度函数、自相关函数和互相关函数等频谱分析函数来进行简单的离线故障诊断。 - The various functions inside the virtual spectrum analyzer introduced in the paper is time domain wave analysis , fft transfer , ifft transfer , cross analysis , and so on , which are all described in function controls . finally , this paper introduce the assemble of intelligent controls - oriented virtual instrument . and use classical signals and industrial practices to demostrate the accurate of virtual spectrum analyzer
