The problem of reconstructing a piecewise constant function from a finite number of its Fourier coefficients perturbed by noise is considered. A reconstruction method, based on the computation of the ...

In this paper we offer a method for constructing functions with many gaps in their supports and in the supports of their Fourier transform. As a result we answer a question of Benedicks [Ben1] and we ...

The Constant-Q transform modifies the STFT such that the frequency bins are logarithmically spaced. Further, the windowing function is adjusted with center frequency so that the width of each bin too ...

Limitations of the FFT-EM Technique FFT can transform a limited range of waveform data, and a window weighting function has to be applied to the waveform to compensate for the spectral leakage, which ...
