ExpWin

Advanced Analysis Library Only

AnalysisLibErrType ExpWin (double arrayX[], int numberOfElements, double final);

Purpose

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

Yi = Xieai

where
f is the final value
n is the number of elements in arrayX

Parameters

Input
Name Type Description
numberOfElements integer Number of elements in the input array, arrayX.
final double-precision Final value of the exponential window function.

Default Value: 0.01.
Output
Name Type Description
arrayX double-precision array On input, the input signal.

On output, the signal after ExpWin applies the exponential window.

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.
