NettetYou can process your signal data using Hilbert-Huang Transform (HHT) which is the combination of Empirical Mode Decomposition (EMD) and Hilbert Spectrum Analysis (HSA) with Matlab or Python. In Matlab or Python, there is the HHT method that you can use directly and do not need to calculate the Instantaneous Frequency (IF) by yourself. NettetUse the pspectrum function with default settings to estimate the power spectrum of the signal. Use the estimate to compute the instantaneous frequency. [p,f,t] = pspectrum …
