Abstract
Processing signals containing interharmonics by empirical mode decomposition, gets a stable component of intrinsic mode functions. Then, get the instantaneous amplitude and instantaneous frequency for each intrinsic mode function components by Hilbert transform, to detect the parameters of interharmonics. Timely, the time, amplitude, frequency of interharmonics can be accurately determined. Simulation studies show the feasibility and effectiveness of the method.
