A new open-source C++ library called FFTM brings portable distributed 3D and 4D fast Fourier transforms to CUDA and HIP multi ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last year. Click-through for the notes or check out the video below the break ...

A new simulation study compares Fourier, wavelet, and direct time-domain fitting methods for analyzing short and non-stationary NMR signals, revealing where each approach excels and how spectrograms ...

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight ...

In Chap. 6 we saw that the discrete Fourier Transform (DFT) could be used to perform convolutions. In this chapter we look at the computational requirements of the DFT and derive some fast algorithms ...

Create an account to access more content and features on IEEE Spectrum, including the ability to save articles to read later, download Spectrum Collections, and participate in conversations with ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

Introduction: The Wall Where Effort Doesn't Lead to GrowthIf the output of computational processing is leveraged by algorithms, couldn't the output of a business also be leveraged by algorithms? This ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...

In January, four MIT researchers showed off a replacement for one of the most important algorithms in computer science. Dina Katabi, Haitham Hassanieh, Piotr Indyk, and Eric Price have created a ...
