The Comparative Analysis of Fourier Transformation and Hilbert Huang Transformation Based on Dynamic EEG Data
Yifeng Li, Lihui Zhang, Baohui Li, Jin Kao Zhao, Haixia Wang, Rong Lin · 2017
The basic law and method of Fourier transformation and Hilbert Huang transformation is introduced.Taking the obtained dynamic EEG data under +Gz acceleration as an example, EEG change feature under +Gz acceleration is analyzed ,and Fourier transformation spectrum graph and Hilbert Huang transformation spectrum graph are compared, then the time-frequency characteristics of the two methods are made analysis and comparison.
