Advantages of Blackman Window over Hamming Window …

WebThat means that for the same M, more smoothing occurs by using a Blackman window and the transition region of the FIR filter response becomes larger. The Blackman filter has lower side lobes ( - 57 d B ) vs . - 13 d B for a rectangular filter so there will be less ripple in the frequency response of the FIR filter ( in both the passband and the ...
