Hello,
I read this statement in one of university handouts and can't figure it out...
"If the signal's frequency content goes all the way down to zero ("DC") then its bandwidth must be twice its centre frequency and its fractional bandwidth equals two. This is a strictly baseband signal"
So we know that the frequency of the DC signal is 0, this means fH(upper freq) and fL(lower freq) both equal 0, so its BW = 0 and so does its center frequency (f mid)...
