taming spectral leakage

Chopping a signal into a finite chunk smears its spectrum — spectral leakage. Tapering the chunk with a window (Hann, Hamming, Blackman) trades a wider main lobe for much lower side lobes, cleaning up the spectrum. Educational tool.

Governing equation

w (n) = 0.5 [1 - cos (\frac{2 π n}{63})]

Reading this result: The Hann window drops side lobes well below the rectangular case, trading a slightly wider main lobe for far cleaner spectral separation.
