blackmanharris (Signal Processing Toolbox)

Compute a minimum 4-term Blackman-harris window

Syntax

```
w = blackmanharris(n)
```

Description

w = blackmanharris(n) returns an n-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:

```
N=32;
wvtool(blackmanharris(N))
```

Algorithm

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

where .

The coefficients for this window are

a₀
=
0.35875

a₁
=
0.48829

a₂
=
0.14128

a₃
=
0.01168

a₀	=	0.35875
a₁	=	0.48829
a₂	=	0.14128
a₃	=	0.01168
