Well, 10dB of gain is a 10x increase in absolute signal, but 12dB of gain would be about 16x the signal. dB = 10 * log(S1/S2) where S1 and S2 are the absolute strengths of two signals you're finding the dB of difference between. The regular absolute-value scale and logarithmic scale of dB "cross" at the factor of 10; so 10dB = 10x, but that's the only place that's true (at least, I think it is, off the top of my head). -Kadin. |
