Algorithm based on zero-crossing and extremum estimation to obtain instantaneous frequency and instantaneous amplitude

According to Hilbert-Huang Transform (HHT) theory, the signal's Intrinsic Mode Function (IMF) is extracted by Empirical Mode Decomposition (EMD). Its time-frequency-amplitude spectrum and marginal spectrum are obtained by Hilbert transform. In the basis of summarizing the limitation of the Hilb...
