Power-of-Cosine Window Family
Definition:
(4.29) |
where is a nonnegative integer.
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.
