Open Live Script

Generate two Tukey windows of length N = 64:

  • The first window has α = 1/4. α is the ratio of tapered window section length to constant section length.

  • The second window has α = 3/4.

Display the two windows.

H14 = sigwin.tukeywin(64,1/4);
H34 = sigwin.tukeywin(64,3/4);

wvt = wvtool(H14,H34);
legend(wvt.CurrentAxes,'\alpha = 1/4','\alpha = 3/4')

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 \alpha = 1/4, \alpha = 3/4.

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

H = sigwin.tukeywin(16);

win = generate(H)
win = 16×1
