i m doing analysis ob ball bearing. i have obtained bearing stiffness for different orientation of balls during ball bearing rotation. so i have a graph of bearing stiffness vs time . now i have to take out fft of the values in order to get peak point showing frequency of rotation. please tell me how to do it and how to plot the fft.

doc fft
doc abs
doc log10
doc plot
