The Feedforward Short-Time Fourier Transform [PDF]

IEEE Transactions on Circuits and Systems II: Express Briefs, 2016
This brief presents the feedforward short-time Fourier transform (STFT). This new approach is based on reusing the calculations of the STFT at consecutive time instants.

SPECTRUM ANALYSIS OF TRANSIENTS USING THE SHORT-TIME FOURIER TRANSFORM

, 2021
The aim of this paper is to analyse the spectrum of real transients from a LV network. The spectrum is obtained using the Short-Time Fourier Transform (STFT). The MATLAB function spectrogram is used to obtain the STFT.

Switches Faults Analysis of Voltage Source Inverter (VSI) using Short Time Fourier Transform (STFT)

International Review on Modelling and Simulations (IREMOS), 2014
Three-phase voltage source inverter (VSI) play a very important role in the present industrial life. The knowledge and information about faults characteristic of the VSI is important to prevent failure of equipment, data losses, high maintenance and economic losses.

Adaptive Short Time Fourier Transform (STFT) Analysis of seismic electric signal (SES): A comparison of Hamming and rectangular window

2012 IEEE Symposium on Industrial Electronics and Applications, 2012
Seismic electric signal (SES) is one of features for predicting earthquakes (EQs) because of its significant changes in the amplitude of the signal prior to the earthquake. This paper presents detailed analysis of SES recorded prior to earthquake that occurred in Greece in the period from January 1, 2008 to June 30, 2008.

Separation of formants from glottal impulses in high-resolution spectrograms using higher-order short-time Fourier transform (STFT) phase derivatives

The Journal of the Acoustical Society of America, 2004
The channelized instantaneous frequency of a signal x(T) is CIFx(ω,T)=(∂/∂T)arg(Fh(ω,T)), where Fh is the short-time Fourier transform of x(T) using window function h. The local group delay of a signal is LGDx(ω,T)=−(∂/∂ω)arg(Fh(ω,T)). For each point Fh(ω0,T0) in the STFT, the f−t coordinates [CIF(ω0,T0),t−LGD(ω0,T0)] pinpoint the local mean of the ...
