Exact Blackman Window (DSP Module)
Applies an Exact Blackman window to the input signal X.
 |
X is the first input sequence. |
 |
Exact Blackman{X} is the input signal with the Exact Blackman window applied. |
Exact Blackman Window Details
If y represents the output sequence Exact Blackman{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.
