class Hamming(*args)

Hamming filtering windows.

Notes

The Hamming windows is implemented using the formula:

w(t) = C(\alpha - (1-\alpha)\cos(2\pi t))\fcar{[0,1]}{t}

with C = \frac{1}{\alpha^2 + (1-\alpha)^2/2} and \alpha=25/46.

The value of \alpha minimizes the amplitude of the first side lobe of its Fourier transform.

The normalization constant C is such that \int_{0}^{1} w(t)^2\di{t} = 1.
