This is an exam question that trips up even some of the best students.
See what you make of it!

Q: Is this statement correct: 'The signal level at the modem input
increased by 2dBmV going from +3dBmV to +5dBmV.'

Your pal, CD.
5-3=2. dBs, pineapples, whatever.
Very brave, John! I think the lack of response thus far indicates how
terrified the great and the good here are of getting it wrong, 'cos
those at the top have the farthest to fall in terms of reputation.
I'll provide the answer the same time tomorrow and we'll see if
there's any other brave souls out there. ;-)
If I have a meter that shows dBmV, and it says 3 and I crank up the
input so it says 5, it went up by 2.

Do you have a counter-case? 3+2 equals something that's not 5?
I'm sure I could find someone teaching mathematics like that in our
wonderful modern school system in no time at all LOL.
