Kaiser-Bessel. The K-B window produces improved side-lobe attenuation resolution
at the base and is similar to BH4 window for frequency resolution. It is very useful
for looking for frequency components closer to the noise floor.
BH4 (Blackman-Harris). The BH4 window provides very good frequency resolution
at the bin frequency but has less side-lobe attenuation.
Saramaki Rajan. This is a Tektronix-developed window similar to Kaiser-Bessel.
This window provides a slight improvement over the Kaiser-Bessel window for
digital input signals and is also very useful for looking for frequency components
closer to the noise floor.
