blackmanharris - Minimum 4-term Blackman-Harris window

Syntax

w = blackmanharris(L)

Description

w = blackmanharris(L) returns an L-point, minimum , 4-term Blackman-Harris window in the column vector w. The window is minimum in the sense that its maximum sidelobes are minimized.

Examples

Create a 32-point Blackman-Harris window and display the result using WVTool:

L=32;
wvtool(blackmanharris(L))

Algorithm

The equation for computing the coefficients of a minimum 4-term Blackman-harris window is

where and the window length is .

The coefficients for this window are

a₀ = 0.35875

a₁ = 0.48829

a₂ = 0.14128

a₃ = 0.01168
