stationary datum meaning in English
冻结基面
Examples
- Non - stationary data processing methods and instantaneous frequency
非平稳数据处理方法与瞬时频率 - Emd method is local adaptive . lt not only can be used to analyse linear data , but also can be used to analyse nonlinear and non - stationary data
Emd方法是一种局部自适应方法，不仅适用于线性时间序列的分析，而且适用于非线性和非平稳时间序列的分析。 - Fourier transform method use high order frequency to analyse and imitate nonlinear and non - stationary data . emd method based on local characteristic time scale of the data is more fit to analyse nonlinear and non - stationary data than fourier transform method
Emd基于信号的局部时间特征尺度分析原信号，克服了傅里叶变换用高次谐波频率分量拟合非线性、非平稳信号的缺点。
