Abstract: As a Fast algorithm of Discrete Fourier Transform (DFT), Fast Fourier Transform (FFT) can quickly analyze discrete signal spectrum and is widely used in communication, radar, medical imaging ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

Package fft provides an efficient radix-2 fast discrete Fourier transformation algorithm in pure Go. This code is much faster than existing FFT implementations and uses no additional memory. The ...

This paper introduces a new encryption method aimed at improving the cryptography process through the use of splitting radix Fourier Transform technique called Split-Radix Fast Fourier Transforms ...

The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain ...

Abstract: This letter presents a far-field pattern synthesis solution for arbitrary conformal arrays employing a near-field virtual equivalent source-based iterative fast Fourier transform (NFVES-IFFT ...

Add a description, image, and links to the inverse-fast-fourier-transform topic page so that developers can more easily learn about it.

According to the manufacturer, the new product will allow designers to share 3D images and motion files, furthering collaboration and centralisation of data. Designers will have a real-life ...
