Blackman Function -- from Wolfram MathWorld

An apodization function given by A(x)=(21)/(50)+1/2cos((pix)/a)+2/(25)cos((2pix)/a), (1) which has full width at half maximum of 0.810957a. This function is defined so that the coefficients are approximations in the general expansion A(x)=a_0+2sum_(n=1)^inftya_ncos((npix)/b), (2) to a_0 = (3969)/(9304) approx 0.42659 (3) a_1 = (1155)/(4652) approx 0.24828 (4) a_2 = (715)/(18608) approx 0.038424, (5) which produce zeros of I(k) at ka=7/4 and ka=9/4. The corresponding instrument...
