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 ...

Mel Frequency Cepstrum Coefficients (MFCC) has been widely applied in voice interaction for feature extraction, where Fast Fourier Transform (FFT) takes up massive power consumption and area in the ...
