The only FAQ I can find under comp.dsp is for audio file formats. I'm interested in a summary of different kinds of windowing that would be usable with continuous Fourier transforms. It would seem that this should at least be in a general coverage technical FAQ for this group, but such an FAQ has not yet been found. So maybe if someone knows this stuff they could start by posting some summary. I've wondered if it is feasible to use (1-cos(x))/2 with x=0..2*pi as a sampling window. I'd like to know what the effects, advantages, and disadvantages of different windows are, and how to interprete the data gotten from with them. -- /***********************************************************************\ | Phil Howard --- KA9WGN --- pdh@netcom.com | "The problem with | | depending on government is that you cannot depend on it" - Tony Brown | \***********************************************************************/
