DiscreteWindow2D

DiscreteWindow2D[N, "type"] returns an N×N window sequence with circular symmetry of type given by type.

DiscreteWindow2D[{N₁,N₂}, "type"] returns an N₁×N₂ window sequence with rectangular symmetry of type given by type.

DiscreteWindow2D[N, "Kaiser",

] returns an N×N Kaiser window sequence.

DiscreteWindow2D[{N₁,N₂}, "Kaiser",

] returns an N₁×N₂ Kaiser window sequence with optional adjustable shape parameter

The default value of the Kaiser shape parameter is

=3.0, with typical values in the range 1≤

Available window types include the following:

fixed	adjustable
Rectangular or Box	Kaiser
Bartlett or Triangular
Blackman
Hamming

The window type of the nonadjustable windows may also be selected using option WindowType. The default setting is WindowType
