WebDec 1, 2014 · The S transform is widely used in time-frequency analysis (TFA). However, the standard S transform suffers from the poor energy concentration in time-frequency distribution (TFD). In this study, an adaptive Dolph–Chebyshev window instead of the Gaussian window-based S transform and its fast realisation strategy are introduced for … Webchebwin: Dolph-Chebyshev window coefficients Description Returns the filter coefficients of the n-point Dolph-Chebyshev window with a given attenuation. Usage chebwin (n, at) Arguments n length of the filter; number of coefficients to generate. at dB of attenuation in the stop-band of the corresponding Fourier transform. Value
