William,
could you please be more specific?
Why do you think "high resolution" may be somehow special?
Where exactly is your problem with creating filter functions?
What do you expect from the filtering process? Enhanced periodicities?
Did you already have a look at Fourier spectra of your samples?
Regards
Herbie
