HammingWindow()

std::vector< double > MayaFlux::Nodes::Generator::HammingWindow

(

size_t

length

)

Creates a Hamming window function.

Parameters

length

Number of samples in the window

Returns

Vector containing the window function values

The Hamming window is similar to the Hann window but doesn't reach zero at the edges. It offers different spectral characteristics and is often used in:

• Signal processing
• Filter design
• Spectral analysis

Mathematical formula: w(n) = 0.54 - 0.46*cos(2π*n/(N-1))
