Time-varying Lifting Structures For Single-tree Complexwavelet Transform [PDF]
, 2012 In this paper, we describe a single-tree complex wavelet transform method using time-varying lifting structures. In the dualtree complex wavelet transform (DT-CWT), two different filterbanks are executed in parallel to analyze a given input signal, which

Pulse Signal Analysis Method Based on Improved HHT [PDF]
Jisuanji gongcheng, 2019 The traditional Hilbert-Huang Transform(HHT) has low accuracy in Empirical Mode Decomposition(EMD) when processing pulse signals,and there are mode mixing problems.In response to this problem,this paper proposes an improved HHT method.Combined with Time ...

On Finite Hilbert Transforms [PDF]
Transactions of the American Mathematical Society, 1975 Let E be a bounded measurable subset of the real line. The finite Hilbert transform is the operator HE defined on one of the spaces LP(E) (1 1, the Hilbert transform of f at x is defined by (1) Hf(x) = li (rmi) f f(tXt -x) 1dt, provided this latter limit exists. It is known that if f is in LP(R), for p > 1, then Hf exists a.e.

An Application to Transient Current Signal based Induction Motor Fault Diagnosis of Fourier-Bessel Expansion and Simplified Fuzzy ARTMAP [PDF]
, 2013 The start-up transient signals have been widely used for fault diagnosis of induction motor because they can reveal early defects in the development process, which are not easily detected with the signals in the steady state operation. However, transient

The Hilbert transform of a measure
Journal d'Analyse Mathématique, 2010 Let $\fre$ be a homogeneous subset of $\bbR$ in the sense of Carleson. Let $μ$ be a finite positive measure on $\bbR$ and $H_μ(x)$ its Hilbert transform. We prove that if $\lim_{t\to\infty} t \abs{\fre\cap\{x\mid\abs{H_μ(x)}>t\}}=0$, then $μ_s(\fre)=0$, where $μ_\s$ is the singular part of $μ$.
