General Cosine Window (Not in Base Package)

Applies a general cosine window to the input signal X. Details

X is the input signal.
Cosine Coefficients is the coefficients that define the general cosine window.

Note  If Cosine Coefficients is an empty array, the VI sets GenCos{X} to an empty array, even if X is not empty.
GenCos{X} is the input signal with the general cosine window applied.
error returns any error or warning from the VI. Refer to Signal Processing Error Codes for more information about these conditions.

General Cosine Window Details

If a represents the Cosine Coefficients input sequence and y represents the output sequence GenCos{X}, the General Cosine Window VI obtains the elements of y from

for i = 0, 1, 2,…,n-1

,

where n is the number of elements in X, and m is the number of Cosine Coefficients.
