In structural health monitoring (SHM), uncertainties from environmental noise and modeling errors affect damage detection accuracy. This paper introduces a new concept: the Fast Fourier Transform ...

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 ...

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.

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 ...

#1 Publication focused exclusively on Interpolation, ie determining value from the existing values in a given data set. #1 Publication focused exclusively on Interpolation, ie determining value from ...

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 ...

Algorithms have taken on an almost mythical significance in the modern world. They determine what you see on social media and when browsing online, help form people’s belief systems, and impact the ...
