Open Live Script

Generate two Kaiser windows of length N = 64:

  • The first window has an attenuation parameter β = 5.

  • The second window has β = 15.

Display the two windows.

H05 = sigwin.kaiser(128,5);
H15 = sigwin.kaiser(128,15);

wvt = wvtool(H05,H15);
legend(wvt.CurrentAxes,'\beta = 5','\beta = 15')

Figure Window Visualization Tool contains 2 axes objects and other objects of type uimenu, uitoolbar, uipanel. Axes object 1 with title Time domain, xlabel Samples, ylabel Amplitude contains 2 objects of type line. Axes object 2 with title Frequency domain, xlabel Normalized Frequency (\times\pi rad/sample), ylabel Magnitude (dB) contains 2 objects of type line. These objects represent \beta = 5, \beta = 15.

Generate a Kaiser window with length N = 16 and the default β = 1/2. Return its values as a column vector. Show information about the window object. Display the window.

H = sigwin.kaiser(16);

win = generate(H)
win = 16×1
