where

Properties:
- The first
terms of the window's Taylor expansion, evaluated at the endpoints are identically 0 .
- Roll-off rate
dB/octave.
Special Cases:
-
Rectangular window
-
MLT sine window
-
Hann window (``raised cosine'' = ``
'')
-
Alternative Blackman (maximized roll-off rate)
Thus,
windows parametrize
-term Blackman-Harris windows
(for
) which are configured to use all degrees-of-freedom to
maximize roll-off rate.
