C# 
public static WindowFunction BlackmanHarris(
	int length
)

Parameters

length  Int32
The length of the window.

Return Value

WindowFunction
A WindowFunction that represents a 4 term Blackman-Harris 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

ArgumentOutOfRangeExceptionlength is less than or equal to zero.

BlackmanHarris(Int32, WindowSampling)

Returns a 4 term Blackman-Harris window of the specified length and symmetry.
C# 
public static WindowFunction BlackmanHarris(
	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

WindowFunction
A WindowFunction that represents a 4 term Blackman-Harris 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

ArgumentOutOfRangeExceptionlength is less than or equal to zero.
