Applies a Blackman window to the input signal 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 Window VI obtains the elements of Y using the following formula:

yi = xi[0.42 – 0.50cos(w) + 0.08cos(2w)]

for i = 0, 1, 2, …, n – 1

where n is the number of elements in X and .
