~ @9:35 , how T can determine the freq domain graph? as per your saying - if I capture constant/same freq signal for different T, I am going to get different graphs??? Thanks
in 10:15 and 12:30, why some peaks of the sub-carriers are negative? Some of the sinc functions (scalated with their corresponding complex number) appear to be up side down... why is that?

Why is it always displayed in frequency domain graph the carriers are the same amplitude? If we use QAM, carriers are different magnitude, right?
Dear sir, I have a doubt regarding QAM,
If I 16 QAM gives a straight line in the constellation, what does it mean?
