The FFT is a digital implementation of the Fourier transform. Thus, the FFT does not yield a continuous spectrum. Instead, the FFT returns a discrete spectrum, in which the frequency content of the waveform is resolved into a finite number of frequency lines, or bins.
FFT waveform analysis module designed Beanair comes with advanced features:
- Power spectral density and a new window displays
- PPV calculation: PPV value in mm/s , Frequency, Amplitude
