Oscilloscope Reference Hamming window
Hamming window
This window is unique in that the time domain shape does not taper all the way to zero at the ends. This
makes it a good choice if you wanted to process the real and imaginary parts of the spectrum off line and
inverse tran
sform it back to the time domain. Because the data does not taper to zero, you could remove
the effect of the window function from the result.

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