Gaussian Window VI

Owning Palette: Windows VIs

Requires: Full Development System

Applies an asymmetrical Gaussian window to the input sequence X. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.

Gaussian Window (DBL)

	X is a real vector.
	standard deviation is the standard deviation of the Gaussian window normalized to the length of X. The default is 0.2.
	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.

Gaussian Window (CDB)

	X is the complex valued input sequence.
	standard deviation is the standard deviation of the Gaussian window normalized to the length of X. The default is 0.2.
	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.

Gaussian Window Details

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

for i = 0, 1, … , n–1

where n is the number of elements in X, m = (n–1)/2.0, and is the standard deviation of the Gaussian window.

Example

Refer to the Window Comparison VI in the labview\examples\Signal Processing\Windows directory for an example of using the Gaussian Window VI.
