论文题目:The empirical mode decomposition and the
Hilbert spectrum for nonlinear and
non-stationary time series analysis
问题:
1.论文的p929公式7.3上面一端关于最低频率,最高频率的论述,怎么也不能理解,请看过的给予解释
2.论文p932图13b如何能看出7hz和17hz高频能量的间断?
(b) A section of wind data
demonstrating the presence of energetic and intermittent oscillations at 7 and 17 Hz.
谢谢解答。
