Exact Blackman Window (Not in Base Package)

Applies an Exact Blackman window to the input signal X. Details  Example

	X is the input signal.
	Exact Blackman{X} is the input signal with the Exact Blackman window applied.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Exact Blackman Window Details

If y represents the output sequence Exact Blackman{X}, the Exact Blackman Window VI obtains the elements of y from

y_i = x_i[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.

Example

Refer to the Window Comparison VI in the labview\examples\analysis\windxmpl.llb directory for an example of using the Exact Blackman Window VI.
