Advanced Analysis Library Only

AnalysisLibErrType ExBkmanWin (double arrayX[], int numberOfElements);

## Purpose

Applies an exact Blackman window to the input signal. If Y represents the output sequence, ExBkmanWin obtains the elements of Y using the following formula:

for i = 0, . . ., n — 1

where |
| n is the number of elements in arrayX

## Parameters
