摘要：

Hilbert-Huang Transform was used to analyze the anode voltage signal in aluminum reduction cell to increase the resolution of its frequency spectrum. The voltage signal was divided into the high-frequency part and the low-frequency one by Empirical Mode Decomposition method (EMD) to get each Intrinsic Mode Functions (IMF). The IMF included the partial feature of the signal in different time scales were listed. Then Hilbert transform is used to get the instantaneous frequency of each intrinsic mode function. Finally the boundary spectrogram from HHT was compared with the frequency spectrum. The results showed that HHT is obviously more effective then FFT in the given anode voltage signal.
