[[File:Window function and its Fourier transform – Blackman (n = 0...N).svg|thumb|480px|right|Blackman window; {{math|1=''α'' = 0.16}}]]

Blackman windows are defined as:

:<math>w[n] = a_0 - a_1 \cos \left ( \frac{2 \pi n}{N} \right) + a_2 \cos \left ( \frac{4 \pi n}{N} \right),</math>

:<math>a_0=\frac{1-\alpha}{2};\quad a_1=\frac{1}{2};\quad a_2=\frac{\alpha}{2}.</math>
