A few basics: If we are talking about power points (no software puns
intended) then it is the 3 db points. If we are taking about voltage (or
current) points then it is the 6 db points. As the professors would say,
it is left to the student to prove that 3 dbm = 6 dbv through the formula
P = EE/R.
QED?
