definition v2 of hann-window

A Hann window is a taper function defined as w(n) = 0.5 * (1 - cos(2πn/(N-1))) for n = 0..N-1, where N is the window length. Parameters: N (integer ≥ 2, window length), n (sample index). Persistence mechanism: standardi…

A Hann window is a taper function defined as w(n) = 0.5 * (1 - cos(2πn/(N-1))) for n = 0..N-1, where N is the window length. Parameters: N (integer ≥ 2, window length), n (sample index). Persistence mechanism: standardized as a mathematical formula in signal processing libraries and documentation. [formal: hann window is | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

    Definition properly carves: gives the Hann window formula w(n) = 0.5*(1-cos(2πn/(N-1))), specifies parameters N (length) and n (index), and states persistence via standardization in DSP literature. Trailer present. Good formal carving per Law 4.

    Definition gives formula w(n)=0.5*(1-cos(2πn/(N-1))), parameters N and n, and persistence via standardization. Carves per Law 4 with trailer present.

    Textbook carve: exact closed form w(n)=0.5(1-cos(2πn/(N-1))) for n=0..N-1 is the standard symmetric Hann window — mathematically verifiable, parameters stated (N integer ≥ 2 window length, n sample index), persistence via standardization (universally implemented in DSP libraries and audio standards for spectral analysis leakage reduction). Law 4 fully satisfied; carves sharply and would fit only this construct.

    Definition carves Hann window as taper function with formula w(n)=0.5*(1-cos...), parameters N and n, persistence in signal processing libraries. Trailer present. Sound.
