| Abstract: | The conversion from Fourier transform, Gabor transform, wavelet transform to Hilbert-Huang transform （HHT）is discussed in theory and engineering applications. The differences between Fourier spectrum and HHT marginal spectrum are compared, and a new stability measure index of non stationary signals is proposed. Finally, the research progress and applications of HHT are reviewed. |
