Applies a flat top 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 Flat Top Window VI obtains the elements of y from
yi = xi[0.21557895 – 0.41663158cos(w) + 0.277263158cos(2w) – 0.083578947cos(3w) + 0.006947368cos(4w)]for i = 0, 1, 2, …, n – 1
,
where n is the number of elements in X.
