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.

Inputs/Outputs

  • c1ddbl.png X —

    X is a real vector.

  • cdbl.png standard deviation —

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

  • i1ddbl.png Windowed X —

    Windowed X is the input signal with the window applied.

  • ii32.png error —

    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.

    • 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 σ is the standard deviation of the Gaussian window.
