Harmonic-wavelet sample-entropy extracting weak noise


The objective of this paper is to introduce Newland Harmonic wavelets and Richman-Moorman (2000) sample entropy are applied to extract weak cycle jumps. Because some weak vibration signals contained strong noises are very important for fault forecast. Based on harmonic wavelet mesh plot of the vibration signals, we can induce contours of the mesh map with… (More)
