Overload List
Blackman( | Returns a standard Blackman window of the specified length and symmetry. |
Blackman( | Returns a Blackman window of the specified length and symmetry. |
Blackman(Int32, WindowSampling)
Returns a standard Blackman window of the specified length and symmetry.
public static WindowFunction Blackman(
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 Blackman 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. |

double alpha
)
Parameters
- length Int32
- The length of the window.
- sampling WindowSampling
- A WindowSampling value that indicates whether the filter is symmetrical or periodic.
- alpha Double
- A parameter between 0 and 1.
Return Value
WindowFunctionA WindowFunction that represents a Blackman 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. -or- alpha is less than or equal to zero or greater than or equal to one. |
