public static WindowFunction BlackmanNuttall(
int length
)
Parameters
- length Int32
- The length of the window.
Return Value
WindowFunctionA WindowFunction that represents a 4 term Blackman-Nuttall window with a length of length, normalized so the largest value is 1.
Remarks
If the window length is even,
the maximum value of 1 may not appear.
Exceptions
Argument | length is less than or equal to zero. |

Returns a 4 term Blackman-Nuttall window of the specified length and symmetry.
public static WindowFunction BlackmanNuttall(
int length,
WindowSampling sampling
)
Parameters
- length Int32
- The length of the window.
- sampling WindowSampling
- A WindowSampling value that indicates whether the filter is symmetrical or periodic.
Return Value
WindowFunctionA WindowFunction that represents a 4 term Blackman-Nuttall window with a length of length, normalized so the largest value is 1.
Remarks
If the window is symmetrical and the length is even,
the maximum value of 1 may not appear.
Exceptions
Argument | length is less than or equal to zero. |
