Hi,

I want my students to do a frequency analysis of a noisy monofrequential 
signal (by FFT or whatever). What I have in mind is to have a problem 
where the student is offered a downloadable file together with a single 
numerical answer field for entering the obtained signal frequency.

If I had a static data file I would make a published resource out of it 
and hardlink it into the problem file. However, I would like to have 
individual, i.e. random, data files for each student. Is there a way of 
having dynamic data files as resources?
