Dear all,
I need to implement a 4096 point non-symmetric Hann window. The
function window provides several types of symetric windows, including
Hann.
I wonder if computing a 4097 point symmetric window and keeping the
first 4096 yields what I'm looking for.
It depends only on your criteria to make it asymetric.
--> window("hn",4)
ans =
0. 0.75 0.75 0.
--> w = window("hn",5)
w =
0. 0.5 1. 0.5 0.
--> w(1:4)
ans =
0. 0.5 1. 0.5
Is this OK ? window() normalizes the maximum height, not the area. So
trimming the raw result less than its half width keeps its max to 1. And
there is no correction factor to apply to the area to keep it to 1,
since it's not its original value.
