This technique is primarily based on the assumption that the signal can be represented as a sum of time-varying components with different amplitudes and frequencies [ 34 ].
WebNov 26, 2015 · Recently a technique called Hilbert vibration decomposition (HVD) has been proposed [ 4 ]. The HVD extracts the mono-components of a signal by using its analytic form where the first component corresponds to the highest instantaneous amplitude [ 4 ]. Based on HVD a technique is proposed to remove the BW of the ECG signal [ 5 ]. WebJun 10, 2024 · Xia et al.
