In matlab, I tried the following codes to understand different windows(Main lobe and side lobes). Code: x1 = 0.0* cos(2*pi*f1*t +0.2) + 0.85* cos(2*pi*f2*t +1.8) x2 = x1.*blackman(length(x1))' x3 = x1.*hanning(length(x1))' x4 = x1.*hamming(length(x1))' x5 = x1.*bartlett(length(x1))' The same doesn't work for Kaiser. Could someone please explain me this. What is the command to understand Kaiser window in Matlab

Check the documentation doc kaiser Click to expand... What differs Kaiser from the other windows is the Beta - factor. Check the documentation. And a hint when it comes to FFTs; it is worth checking up coherent sampling which might save you some of the issues that windowing can bring.

Just type doc kaiser in the console. Then you will be directed to the help documentation which has examples and links to further information.
