chebwin (Signal Processing Toolbox)

Chebyshev window

Syntax

```
w = chebwin(n,r)
```

Description

w = chebwin(n,r) returns the column vector w containing the length n Chebyshev window whose Fourier transform sidelobe magnitude is r dB below the mainlobe magnitude. The default value for r is 100.0 dB.

Note If you specify a one-point window (set n=1), the value 1 is returned.

Examples

Create a 64-point Chebyshev window with 100 dB of sidelobe attenuation and display the result using WVTool:

```
N=64;
wvtool(chebwin(N))
```
