- Abstract
- In order to detect accurately interharmonics, a detection method based on HHT is presented. Firstly the signals containing interharmonics should be processed by empirical mode decomposition (EMD) to get a stable component of intrinsic mode functions (IMF), then the instantaneous amplitude and instantaneous frequency for each IMF are obtained by Hilbert transforming. A simulation study shows the feasibility and effectiveness of the method.
