Recently, many signal-processing techniques, such as fast Fourier transform, short-time Fourier transform, wavelet transform (WT… Expand This paper presents and analyzes a method for short-circuit fault detection in a permanent-magnet synchronous motor (PMSM). The… Expand The estimation of the instantaneous frequency (IF) of a harmonic complex-valued signal with an additive noise using the Wigner… Expand Abstract Microdiffraction data collected in a scanning transmission X-ray microscope (STXM) are used to obtain phase and… Expand A concise introduction to the concept of fractional Fourier transforms is followed by a discussion of their relation to chirp and… Expand The Wigner higher order moment spectra (WHOS)
are defined as extensions of the Wigner-Ville distribution (WD)
to higher order… Expand Starting from the well-known description of a first-order optical system by means of its symplectic ABCD ray transformation… Expand The Wigner-Ville distribution (WVD) is a valuable tool for time-frequency signal analysis. In order to implement the WVD in real… Expand The paper presents a review of the Wigner distribution function (WDF) and of some of its applications to optical problems… Expand The short-time Fourier transform (STFT), the ambiguity function (AF), and the Wigner distribution (WD) are mixed time-frequency… Expand
