WVTool

Open Window Visualization Tool

Description

Window Visualization Tool is an interactive tool that enables you to visualize time and frequency domain plots of the window vector. You can generate window vectors for a number of common window functions using the Signal Processing Toolbox™ software. See window for a list of supported window functions.

Note

A related tool, Window Designer, is available for designing and analyzing windows.

Open the WVTool

WVTool can be opened programmatically using one of the methods described in Programmatic Use.

Use wvtool to display and compare 64-point Hamming, Hann, and Gaussian windows.

wvtool(hamming(64),hann(64),gausswin(64))

Figure Window Visualization Tool contains 2 axes objects and other objects of type uimenu, uitoolbar, uipanel. Axes object 1 with title Time domain contains 3 objects of type line. Axes object 2 with title Frequency domain contains 3 objects of type line.

Compare 128-point Kaiser windows with different values of β.

wvtool(kaiser(128,1.5),kaiser(128,4.5))

Figure Window Visualization Tool contains 2 axes objects and other objects of type uimenu, uitoolbar, uipanel. Axes object 1 with title Time domain contains 2 objects of type line. Axes object 2 with title Frequency domain contains 2 objects of type line.

Programmatic Use

wvtool(WindowVector) opens the Window Visualization Tool (WVTool) with time and frequency domain plots of the window vector specified in WindowVector. WindowVector must be a real-valued row or column vector. By default, the frequency domain plot is the magnitude squared of the Fourier transform of the window vector in decibels (dB). You can generate window vectors for a number of common window functions using the Signal Processing Toolbox software. See window for a list of supported window functions.

wvtool(WindowVector1,...,WindowVectorN) opens WVTool with time and frequency domain plots of the window vectors specified in WindowVector1, …, WindowVectorN.

H = wvtool(...) returns the figure handle, H.
