We extend the data before using EMD, and then we extend the IMF based on making signal before using Hilbert transformation.
对信号进行外延后进行EMD，然后利用掩膜信号对IMF分量进行延拓后再进行希尔伯特变换；
An improved monitoring method is proposed. "Reducing noise with symmetry decomposition" is used to reduce noise and Hilbert transformation is used to extract characteristic signals.
提出了对称补偿降噪以及利用希尔伯特变换方法进行降噪和特征信号提取。
