• Improved EMD on ECG signals: Ahmadi et al.[2024] presented an Improved EMD and compared with other types of EMD. Results show the proposed algorithm provides no spurious IMF for these functions and is not placed in an infinite loop. EMD types comparison on ECG(Electrocardiography) signals reveal the improved EMD was an appropriate algorithm to be used for analyzing biological signals. Webmagnetic field variations in HV equipment, and provision of the 3D (n–q–ψ) parameters for PD recognition. Time–frequency analysis techniques, such as the Fourier transform [5], and the wavelet transform [4], have been investigated for non-stationary signal feature extraction. These techniques require an understanding of their respective
