Windows

In both digital filter design and power spectrum estimation, the choice of a windowing function can play an important role in determining the quality of overall results. The main role of the window is to damp out the effects of the Gibbs phenomenon that results from truncation of an infinite series.

The toolbox window functions are shown in the table below.

Graphical User Interface Tools

Two graphical user interface tools are provided for working with windows in the Signal Processing toolbox:

Window Design and Analysis Tool (wintool)
Window Visualization Tool (wvtool)

Refer to the reference pages for these tools for detailed information.
