Vibration-Monitoring
- The HHT represents a time-dependent series in a two-dimensional (2-D) time-frequency domain by extracting instan eous frequency components within the signal through an Empirical Mode Decomposition (EMD) process. The analytical background of t

- emd 分解程序 希尔伯特换变换的程序有图-emd decomposition process Hilbert transform procedures change map
EMD-HHT
- 用于机械故障诊断中的EEMD 分解和HHT 变换，我当初就是用的这个程序，稍加修改就可以满足您的要求-EMD-HHT,this program is correct

- HHT就是先将信号进行经验模态分解（EMD分解），然后将分解后的每个IMF分量进行Hilbert变换，得到信号的时频属性的一种时频分析方法。 -HHT is the first signal empirical mode decomposition (EMD decomposition), then each IMF component decomposition of the Hilbert transform, time-frequency frequency analysis meth

- 1998 and Huang et al., 1999 is a recently developed method used for analyzing the nonlinear and non-stationary signal. The supreme innovations of HHT are the establishment of the concept of intrinsic mode function (IMF) and importing of empirical mod

- 主要用於分析時序資料，HSA(Time,IF,AM) && HHS(IF,HoloIF,HoloAM) 這是從不同面相看資料，時間、瞬時頻率、振福 瞬時頻率、波峰瞬時頻率、波峰瞬時振幅 這樣就可以看到被感應器偵測到的訊號中有不同空間頻率的能量疊加在整個 RAW 資料之中 Data -> [CEEMD] -> IMF IMF -> [AM-FM] -> AM,FM FM -> [NDQ] -> IF IMF波
