FRF using Fast Fourier transform
显示 更早的评论
As to plot FRF(output) using FFT we plot cross(xf)/auto(ff) v/s frequency. The to plot the Frequency response of input force what we plot auto(FF) v/d frequency ????

hello
so you mean you want to plot the autospectrum of the input, then yes, we plot auto(FF) v/s frequency
- FRF of solely the input is not meaningful
