Applies a Hamming window to the input signal X. The data type you wire to the X input determines the polymorphic instance to use.

Details  Example

Use the pull-down menu to select an instance of this VI.

Hamming Window (DBL)

X is a real vector.
Windowed X is the input signal with the window applied.
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Hamming Window (CDB)

X is the complex valued input sequence.
Windowed X is the input signal with the window applied.
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Hamming Window Details

If y represents the output sequence Windowed X, the Hamming Window VI obtains the elements of y from

yi = xi[0.54 – 0.46cos(w)]

for i = 0, 1, 2, …, n – 1,

where n is the number of elements in the input sequence X.

Example

Refer to the Window Comparison VI in the labview\examples\analysis\windxmpl.llb for an example of using the Hamming Window VI.
