Abstract: This paper implements the Fast Fourier Transform (FFT) algorithm for signal data processing using Open Computing Language (OpenCL). A parallel algorithm model suitable for staged FFT across ...

Abstract: The ever-increasing demands for signal processing speed and accuracy in modern communication or radar systems underscore the pivotal role of Matched Filtering (MF) as a critical signal ...

Early warning system earthquake alerts exploit the time delay that the surface waves have in reference to the P waves and estimate the magnitude based on the interpretation of the specific parameters ...

Being done in PipelineC it's possible to automatically pipeline both the math of some RISC-V instructions as well as the arbitrary pure functions that describe the custom compute pipelines attached to ...

Add a description, image, and links to the fft-algorithm topic page so that developers can more easily learn about it.

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 ...

In part 2 of this series, we looked at a swept-tuned spectrum analyzer and how it could sweep a frequency span of interest from 1 MHz to 1.1 MHz with a sweep time of 50 msec. As Figure 1 shows, the ...

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 ...
