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 ...

Abstract: The Discrete Fourier Transform (DFT) algorithm is widely used in signal processing and communication systems to transform the signal to the frequency-domain. As real-time signal analysis is ...

Abstract: A discrete Fourier transform (DFT)-based multitarget separation method is proposed in this letter. This method can accurately estimate the direction-of-arrivals (DOAs), amplitudes, and ...

A Discrete Fourier Transform (DFT), a Fast Wavelet Transform (FWT), and a Wavelet Packet Transform (WPT) algorithm in 1-D, 2-D, and 3-D using normalized orthogonal (orthonormal) Haar, Coiflet, ...

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 ...

The semiconductor industry continues to face numerous challenges as designs approach reticle limits, process nodes evolve and engineering resources become increasingly stretched. It is essential to ...

Despite being the most abundant element in the universe, making cheap, clean hydrogen here on Earth has been a surprisingly tough nut to crack. “Hydrogen has always been plagued with a couple problems ...

Introduction: With the rapid advancement of industrialization and the prevalent occurrence of haze weather, P M 2.5 contamination has emerged asa significant threat to public health and environmental ...

Fourier transform is a key method for analyzing signals in both time and frequency domains. The FFT is a computational algorithm that efficiently computes the discrete Fourier transform (DFT) and its ...
