Open Live Script

Generate two Hann windows:

  • The first window has N = 64 and is symmetric.

  • The second window has N = 63 and is periodic.

Display the two windows.

Hs = sigwin.hann(64,'symmetric');
Hp = sigwin.hann(63,'periodic')
Hp = 
            Name: 'Hann'
    SamplingFlag: 'periodic'
          Length: 63


wvt = wvtool(Hs,Hp);
legend(wvt.CurrentAxes,'Symmetric','Periodic')

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 Symmetric, Periodic.

Generate a symmetric Hann window with N = 16. Return the window values as a column vector. Show information about the window object. Display the window.

H = sigwin.hann(16);

win = generate(H)
win = 16×1
