Applies a Blackman-Nuttall 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 Blackman-Nuttall Window VI obtains the elements of y using the following formula:
yi = xi [0.3635819 – 0.4891775cos(w) + 0.1365995cos(2w) – 0.0106411cos(3w)]for i = 0, 1, 2, … , n–1
where n is the number of elements in X and w =
.
