Classic Blackman

The so-called ``Blackman Window'' is the specific case for which $ \alpha_0 = 0.42$ $ \alpha_1 = 0.5$ , and $ \alpha_2 = 0.08$ . It has the following properties:

  • Side lobes roll off at about $ 18\dB $ per octave (like Hann)
  • Side-lobe level is about $ 58$ dB (worst case)
  • One degree of freedom used to increase the roll-off rate from 6dB/octave (like rectangular) to 18 dB per octave by matching amplitude and slope to 0 at the window endpoints
  • One degree of freedom is used to minimize side lobes (like Hamming)
  • One degree of freedom is used to scale the window
