Hi,
I have simple question.
I think it is basic concept for digital communication.
However, I'm a little bit confusion on this.
Maybe, I'm missing some point.
In many books, when the bandwidth of lowpass equivalent signal is B, the BW of the transmitted signal is 2B.
Why? Do you provide the reason or give me some reference to understand this?
Thanks in advance.
