Inputs/Outputs

  • c1dcdb.png X —

    X is the complex valued input sequence.

  • 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 y represents the output sequence Windowed X, the Hanning Window VI obtains the elements of y using

    yi = 0.5xi[1 – cos(w)]

    for i = 0, 1, 2, …, n – 1,

    where n is the number of elements in X.

    A Hanning window is also called a Hann window.
