Rotating machinery faults can induce characteristic modulation effects in a vibration signal,
and their diagnosis can thus be conducted by extracting fault-induced modulation features …

This article provides a general overview of time-frequency (TF) reassignment and
synchrosqueezing techniques applied to multicomponent signals, covering the theoretical …

In this paper, we introduce a new time-frequency (TF) analysis (TFA) method to study the
trend and instantaneous frequency (IF) of nonlinear and nonstationary data. Our proposed …

Time-frequency (TF) analysis (TFA) method is an important tool in industrial engineering
fields. However, restricted to Heisenberg uncertainty principle or unexpected cross terms …

This paper puts forward a generalization of the short-time Fourier-based synchrosqueezing
transform using a new local estimate of instantaneous frequency. Such a technique enables …

Synchrosqueezing transform (SST) is an effective post-processing time-frequency analysis
(TFA) method in mechanical signal processing. It improves the concentration of the time …

The impulse features in a condition monitoring (CM) signal usually imply the occurrence of a
defect in a rotating machine. To accurately capture the impulse components in a CM signal …

Condition monitoring and fault diagnosis of the planet bearing is key to operational reliability
of the planetary gearbox, and also have remained challenging due to complex modulation …

The short-time Fourier transform (STFT) and the continuous wavelet transform (CWT) are
extensively used to analyze and process multicomponent signals, ie superpositions of …

We analyze the stability properties of the Synchrosqueezing transform, a time-frequency
signal analysis method that can identify and extract oscillatory components with time-varying …
