parzenwin - Parzen (de la Valle-Poussin) window

Syntax

w = parzenwin(L)

Description

w = parzenwin(L) returns the L-point Parzen (de la Valle-Poussin) window in column vector w. Parzen windows are piecewise cubic approximations of Gaussian windows. Parzen window sidelobes fall off as .

Examples

Compare 64-point Parzen and Gaussian windows and display the result using sigwin window objects and wintool:

wintool(sigwin.parzenwin(64),sigwin.gausswin(64))

Algorithm

The Parzen window is defined as

The window length is .
