Question: Produce a frequency amplitude plot from discrete data?


I will be collecting motion data. I believe there will be high frequency errors in the data. I would like to convert the data into the frequency domain and view the frequency amplitude. (I have only a slight familiarity with the Fourier Series and Fourier Transform.)

In preparation I generated some example data using
[n*Pi/150,1-cos(n*Pi/150)+er] (n=150) and er is a small random error.
I found the DiscreteTransforms package (Maple10) and the FourierTransform command but I do not really know how to use the data and end up with a frequency amplitude.
I would be most grateful for an illustration or even guidance on how to interpret the examples in maple.
