Those who are interested in windowing might want to take a look
at the following paper.

    "On the Use of Windows for Harmonic Analysis with the Discrete
     Fourier Transform," Harris, Fredric J., Proceedings of the IEEE
     Vol 66, No.1, January 1978.

It discusses the reasons for windowing, and the effects of different types
of windows (Rectangle, Triangle, Hanning, Poisson, Blackman, Kaiser, etc...
to name a few of the more familiar).

I used this many^3 years ago so it may be dated.  If anyone knows of
a contemporary version that includes some "discoveries" in the last 20
years please post a reference.
