WebFeb 16, 2024 · There are more frequencies in the Fourier series: $f_n=n/T$ for $n\in\mathbb {Z}$ (yes, we also talk about negative frequencies). WebFast fourier transform (FFT) is one of the most useful tools and is widely used in the signal processing [12, 14].FFT results of each frame data are listed in figure 6.From figure 6, it can be seen that the vibration frequencies are abundant and most of them are less than 5 kHz. Also, the HSS-X point has greater values of amplitude than other points which …
