fft natural frequency

FFT Fast Fourier Transform - any of the implementations of the DFT, or discrete Fourier transform, that decimates the inputs in time or frequency and then

compute the amplitude and phase versus frequency from the FFT An actual plot of a window shows that the frequency characteristic of a window is a 

The results of the FFT can be used to determine resonant frequencies in a structure which might lead to structural failures in operation REFERENCES Den Hartog 

eral FFT analysis is best suited for heavily damped structures although with the modal damping frequency σ and the undamped natural frequency ωo, i e
