Example sentences for: fft

How can you use “fft” in a sentence? Here are some example sentences to help you improve your vocabulary:

A Fast Fourier Transformation (FFT) based spectral analysis of HRV is performed on all 1001-heartbeat sequences.
However, in the implementation in PKQuest (using Maple) it was observed that the overhead required to set up the FFT approach used more CPU time than the more direct implementation that was finally adopted.
This method estimates the period of a rhythm with the Fast Fourier Transform, then uses that value as a starting point to fit a sinusoid to the data by non linear least squares estimation [ 10 18 ] . This would presumably find a period "in between the cracks" of the original FFT.
where FFT is the Fourier transform of the specific sequence.
There is no reason to presume that the next several data points would be zero and, in addition, perfectly good and real data near the end of the original series are corrupted when they are altered by the smoothing function [ 47 48 37 ] . We prefer to avoid using the FFT for these reasons.
