Applies an exponential 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.

  • cdbl.png final value

    final value specifies the coefficient of the last point of the window.

  • 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 Exponential Window VI obtains the elements of y from

    yi = xiexp(a*i)

    for i = 0, 1, 2, …, n – 1,

    where f is the final value, and n is the number of samples in X.

    You can use the Exponential Window VI to analyze transients.
