Why do we use Blackman window?

The Blackman window is a taper formed by using the first three terms of a summation of cosines. It was designed to have close to the minimal leakage possible. It is close to optimal, only slightly worse than a Kaiser window.

Which windowing technique is best?

The Hamming window is preferred by many due to its relatively narrow main lobe width and good attenuation of the first few side lobes.

How do I use Blackman window?

Solution: Write a MATLAB function, blackman(N), to generate a Blackman window of length N. Apply it to the filter impulse responses using point-by-point multiplication (i.e., using the . * operator). Modify the last example applying the window to the filter's impulse response before taking the Fourier transform.
