Applies an Exact 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 Exact Blackman Window VI obtains the elements of y from

yi = xi[a0 – a1cos(w) + a2cos(2w)]

for i = 0, 1, 2, …, n – 1

,

where n is the number of elements in X,

a0 = 7938/18608, a1 = 9240/18608, and a2 = 1430/18608.
