WebSep 10, 2016 · $\begingroup$ Normally for an FFT the frequency resolution is the inverse of the sample time. So for 0.5s of measurement you will always get 2Hz frequency resolution, independent of sampling rate. However you might be able to get a better resolution locally by interlacing two (or more) FFT's using different number of samples/sample time. WebThe work involves studying and analyzing current FFT software from vendors and open-source developers in order to understand, design, and develop a 3-D FFT-ECP library that could benefit from these existing optimized FFT kernels or will rely on new optimized kernels developed under this framework.
