Hamming Window Blackman Window Harris Window THE ENGINEERING TOOLS The Von Hann function can be expressed simply with only two terms in the cosine series. The Von Hann window function is defined by equation 3. HURON TECHNICAL MANUAL PAGE 248 ( ) hn N n ⎛ ⎞ = 05 . + 05 . cos⎜⎟ ⎝ ⎠ π N N n = − ,..., −101 , , ,..., (3) 2 2 The mainlobe is twice the width of the rectangular windows and its highest sidelobe is attenuated relative to the mainlobe by 32dB. The Hamming window is also a member of the cos(x) series window family. It is an extension of the Von Hann window and is sometimes called the generalised Von Hann window. It is a raised cosine of the form in equation 4. ( ) hn N kn ⎛ ⎞ = 054 . + 046 . cos⎜⎟ ⎝ ⎠ π N N n = (4) − ,..., −101 , , ,..., 2 2 The mainlobe of the Hamming window matches the mainlobe width of the Von Hann, and its main sidelobes attenuate at 43dB relative to the mainlobe. However, the sidelobes do not decay as rapidly as the Von Hann window. A cosine series with three terms, rather than the two for Von Hann and Hamming windows was researched by Blackman. One can view the generalised cosine series over K terms as that in equation 5. hn ( ) ak N kn K ⎛ π ⎞ = ∑ ( )cos⎜⎟ ⎝ ⎠ k= 0 N N n = − ,..., −101 , , ,..., (5) 2 2 For the Blackman window used by Wingen the coefficients a(0), a(1) and a(2) are shown in 6 (Next page). a( 0) = 0. 42659071 a( 1) = 0. 49659062 a( 2) = 0. 07684867 The Harris window introduces a fourth term in the cosine series of 5. Coefficients for the Harris window in Wingen are: (6)
Blackman-Harris Window a( 0) = 0. 3066923 a( 1) = 0. 4748398 a( 2) = 01924696 . a( 3) = 0. 0259983 THE ENGINEERING TOOLS This window has the lowest sidelobe levels supported by Wingen. It is characterised as the minimum four term cosine series Blackman-Harris window. The coefficients used are: a( 0) = 0. 3635819 a( 1) = 0. 4891775 a( 2) = 01365995 . a( 3) = 0. 0106411 HURON TECHNICAL MANUAL PAGE 249 (7)
