Applies a general cosine window to the input signal X. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.

Inputs/Outputs

  • c1dcdb.png X —

    X is the complex valued input sequence.

  • c1ddbl.png Cosine Coefficients —

    Cosine Coefficients is the coefficients that define the general cosine window.

    Note If Cosine Coefficients is an empty array, the VI sets Windowed X to an empty array, even if X is not empty.
  • i1dcdb.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 a represents the Cosine Coefficients input sequence and y represents the output sequence Windowed 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.
