torch.signal.windows.nuttall
torch.signal.windows.nuttall(M, *, sym=True, dtype=None, layout=torch.strided, device=None, requires_grad=False)
Computes the minimum 4-term Blackman-Harris window according to
   Nuttall.
  w_n = 1 - 0.36358 \cos{(z_n)} + 0.48917 \cos{(2z_n)} - 0.13659
  \cos{(3z_n)} + 0.01064 \cos{(4z_n)}

where "z_n = 2 Ï n/ M".
The window is normalized to 1 (maximum value is 1). However, the 1
   doesn't appear if "M" is even and "sym" is True.
Parameters:
      M (int) -- the length of the window. In other words, the
      number of points of the returned window.
Keyword Arguments:
      * sym (bool, optional) -- If False, returns a
        periodic window suitable for use in spectral analysis. If
        True, returns a symmetric window suitable for use in filter
        design. Default: True.
  * **dtype** ("torch.dtype", optional) -- the desired data type
