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

If y represents the output sequence Windowed X, the Cosine Tapered Window VI obtains the elements of y using the following equation:

where ,

n is the number of elements in X, r is the ratio of the total length of the tapered section to the whole signal length as shown below:

If r ≤ 0, the window is equivalent to a rectangular window. If r ≥ 1, the window is equivalent to a Hanning window.
