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 ...

A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the ...

This webinar will describe the FFT function of an oscilloscope in detail. We will cover the settings of the oscilloscope that will affect the FFT result, and how the spectrum analyser function can ...

Sensor fusion is becoming increasingly popular and more complex in automotive designs, integrating multiple types of sensors into a single chip or package and intelligently routing data to wherever it ...

In part 1 of this series, we looked at the formula for the inverse discrete Fourier transform and manually calculated the inverse transform for a four-point dataset. Then, we used Excel’s ...

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 ...

To ensure the success of renewable energy and resource adequacy goals, MISO should follow PJM’s lead in addressing the backlog of projects in its interconnection queue. Currently, MISO has yet to open ...

This article originally appeared in the June’24 magazine issue of Electronic Specifier Design – see ES’s Magazine Archives for more featured publications. EMI/EMC regulations help ensure reliable ...

Abstract: This paper states that Fitting Green's function Fast Fourier Transformation (FG-FFT) algorithm applies to accelerating matrix vector product of higher order Method of Moments (MoM). For ...
