Hi kassen, Thanks for the link. The sync filter is exactly what I am doing. I am applying a rectangular window in the frequency domain (so all bins=0 above the specified freq), which in fact translates into a sync function in the time domain. This way is more efficient than convolving in the time domain with the sync function. I'll have a look at your previous post, with more detail.
And I think it's entirely normal that it turns out to be hard to make a artefact-free brick-wall filter
Yes, I also think so. I am hoping some experienced dsp guru in the list may have some tips. thanks again, eduard
