Abstract:
Hilbert-Huang transform(HHT) is a new method for signal analysis developed by Norden.E.Huang et al in 1998.The concepts for main contents,Empirical mode decomposition,Hilbert spectrum and marginal spectrum of Hilbert-Huang transform(HHT) are introduced.Based on the characteristics of VI's development and application,combining software and hardware,the designed method,which includes hardware,software and panel for the Virtual Signal Analyzer Based on Hilbert-Huang Transform are introduced.Based on the HHT,combined with virtual instrument technology,a Virtual Signal Analyzer is developed successfully.It has provided a new method for signal test and analysis.
