This video explains why the Fast Fourier Transform (FFT) is often called the most important algorithm ever created. Originally developed to help detect hidden nuclear weapons tests during the Cold War ...

Abstract: In this paper an efficient approach to compute Discrete Fourier Transform (DFT) using Radix-3 algorithm, which is a Fast Fourier Transform (FFT), has been presented. It takes less ...

Users can note which content they would like to view more frequently. Instagram is handing users some control in deciding what content they see. The social media giant is allowing users to have a say ...

The module includes both a Python library and a REST API server for remote wavelet analysis. Sample scripts (sample.py, sample_xwt.py) illustrate library usage, while the server enables integration ...

Fast Fourier transform (FFT) using the Cooley–Tukey algorithm for power-of-two sizes and Bluestein's algorithm for non-power-of-two sizes.

Algorithms to compute the quantum Fourier transform over a cyclic group are fundamental to many quantum algorithms. This paper describes such an algorithm and gives a proof of its correctness, ...
