Overload List
Chebyshev( | Returns a Chebyshev window with the specified length and sidelobe attenuation. |
Chebyshev( | Returns a Chebyshev window with the specified length, symmetry, sidelobe attenuation. |
Chebyshev(Int32, Double)
Returns a Chebyshev window with the specified length and sidelobe attenuation.
public static WindowFunction Chebyshev(
int length,
double sidelobeLevel
)
Parameters
- length Int32
- The length of the window.
- sidelobeLevel Double
- The height of the side-lobes relative to the main lobe, in units of 20dB.
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 length is even,
the maximum value of 1 may not appear.
Exceptions
Argument | length is less than or equal to zero. -or- sidelobeLevel is less than or equal to zero. |
Chebyshev(Int32, WindowSampling, Double)
Returns a Chebyshev window with the specified length, symmetry, sidelobe attenuation.
public static WindowFunction Chebyshev(
int length,
WindowSampling sampling,
double sidelobeLevel
)
Parameters
- length Int32
- The length of the window.
- sampling WindowSampling
- A WindowSampling value that indicates whether the filter is symmetrical or periodic.
- sidelobeLevel Double
- The height of the side-lobes relative to the main lobe, in dB.
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- sidelobeLevel is less than or equal to zero. |
