set its color. Finally, click the “Create” button to generate the physical quantity (“lin_1”) of
“pos_err” plus “vel_fbf”, as shown in Fig. 6-20. Other mathematical operations are the
same as that for addition. Not repeat them here. The related icon on the main toolbar area

(3) Fast Fourier transform (FFT)
Click in the main toolbar area to appear the window of Fig. 6-21, and then choose the
required physical quantity to do the Fourier transform. Here, take “pos_err” as an
example. Finally, click the “Run FFT” button to generate the transformed graph, as shown
in Fig. 6-22. To cancel the result of Fourier transform, click . The related icon on the
main toolbar area is described as follows.
