Discover how Fourier Analysis breaks down complex time series data into simpler components to identify trends and patterns, despite its limitations in stock forecasting.

The FIND function allows you to find a text string within another. It returns the position at which a character or string begins within another text string. The output of the above function will be 5, ...

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 ...

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 ...

State-space models (SSMs) are crucial in deep learning for sequence modeling. They represent systems where the output depends on both current and past inputs. SSMs are widely applied in signal ...

The FFT can measure phase angle, but what appears to be a meaningful result might just be the arctangent of a ratio of rounding errors. Throughout this series, we reviewed the fast Fourier transform ...

This RESTful API performs function multiplication using the Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT). Users can send two input functions, and the API computes their ...

In this study, we present a fast algorithm for the numerical solution of the heat equation. The heat equation models the heat diffusion over time and through a given region. We engage a finite ...

Abstract: The periodicity assumption implicit in fast Fourier transform (FFT) techniques can be utilized through time-domain prealiasing to obtain the spectral components of infinite-duration ...
