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.
