HiDavid
I was doing FFT on this data, but I am getting fun spectrum. In the
data there are some big values(they look like outliers). Could I try
remove those big values in order to plot FFT.

Maybe I have to apply hanning window to get right spectrum, Any
suggestions are much welcome.
Many thanks
Zolile
