小弟最近在看N.E.Huang的经典emd论文--The empirical mode decomposition and theHilbert spectrum for nonlinear and
non-stationary time series analysis对其中有些地方不甚理解,望高手解答!
在page20处有这样一段话In some components, such as c1 and c3, the signals are intermittent,then the neighbouring components might contain oscillations of the same scale,but signals of the same time scale would never occur at the same
locations in two different IMF components.
这里是不是说在同一时间区域,信号只在一个imf中振动?
( 楼主 你的意思说的很清楚了,但是没必要连发帖子,如果有热心的,并且有兴趣的会员看见也一定会回复的。毕竟不是所有人每天每时每刻都在线,而且就算是在线也未必有兴趣啊。:@) )
