ABSTRACT: This study presents a comparative analysis of two image enhancement techniques, Continuous Wavelet Transform (CWT) and Fast Fourier Transform (FFT), in the context of improving the clarity ...

Accurate frequency estimation in a wideband digital receiver using the FFT algorithm encounters challenges, such as spectral leakage resulting from the FFT’s assumption of signal periodicity.

In four new studies, researchers found complicated results from experiments on Facebook’s and Instagram’s algorithms, suggesting there was no silver bullet to fixing the platforms. By Mike Isaac and ...

C# implementation of the Goertzel algorithm for DTMF tone (a.k.a. Touch-Tone) detection and localization in audio data. Includes wrappers and extensions for NAudio.

Abstract: The Goertzel algorithm is fairly known algorithm in tone detection systems. This effective realization of a partial Fourier transform is able to evaluate selected spectral bin by a very ...

Abstract: This paper shows that the Goertzel algorithm derivations, which over years can be found in the literature, are either inadequate or inelegant, or even erroneous. Furthermore, the resulting ...

In this repository I store example scripts of some DSP algorithms made in MATLAB. These served an educational purpose when I wrote them, I'm making them public, since I had trouble finding example ...
