CxBkmanWin
Advanced Analysis Library Only
AnalysisLibErrType CxBkmanWin (NIComplexNumber arrayX[], ssize_t numberOfElements);
Purpose
Applies a Blackman window to the complex input signal. If y represents the output sequence arrayX, CxBkmanWin obtains the elements of y using the following equation:yi = xi[0.42 - 0.50cos(w) + 0.08cos(2w)]
for i = 0, 1, 2, ..., n – 1where n is the number of elements in arrayX and
.The function performs the window operation in place; that is, the windowed data replaces the input data.
Parameters
| Input | ||
| Name | Type | Description |
| numberOfElements | ssize_t | Number of elements in arrayX. |
| Output | ||
| Name | Type | Description |
| arrayX | NIComplexNumber [] | On input, the input signal. On output, this parameter returns the input signal with a Blackman window applied. |
Return Value
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
