Hanning, Kaiser-Bessel, and Blackman-Harris Windows: These windows have
various resolution bandwidths and scallop losses (see figures 3--53, 3--54, and
3--55). Choose the one that best allows you to view the signal characteristics you
are interested in. The Blackman-Harris has a low amount of energy leakage
compared to the other windows. The Hanning has the narrowest resolution
bandwidth, but higher side lobes.
