Wolfram Demonstrations Project

This Demonstration investigates the frequency-domain properties of the Kaiser window, a useful tool in signal processing.

The Kaiser window is defined by the formula:

The Fourier transform of the Kaiser window

(where

is treated as continuous) is:

where

is the modified Bessel function of the first kind of zero order.
