You are mistaken. A 3 dB increase in signal level is a 3 dB increase - there's no need to say if power or voltage. The formula for computing an increase is going from power P2 from P1 is. 10 log (P2/P1) or if voltage 20 log (V2/V1). If the voltage rises by a factor of 10, the power rises by a factor of 100, since power is V^2/R. 10 log (100) = 20 dB is the same as 20 log (10) = 20 dB.
