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')

Generate a Kaiser window with length N = 16 and the default β = 1/2. Return its values as a column vector. Write the coefficients to an ASCII file in the current directory. Show information about the window object. Display the window.

H = sigwin.kaiser(16); win = generate(H)
win = 0.9403 0.9550 0.9677 0.9783 0.9868 0.9933 0.9976 0.9997 0.9997 0.9976 
winwrite(H,'kaiser_16'); wininfo = info(H)
wininfo = 4×13 char array 'Kaiser Window' '-------------' 'Length : 16 ' 'Beta : 0.5'
