Twice the signal means twice the voltage, for me.

Greg


Twice the voltage is a 6 db gain. Twice the power is a 3db gain.


Exactly. If I got 1 microvolt, 2 microvolts will be twice the signal.

Greg


No, 2 microvolts would be four times the signal. Remember that power
equals the voltage SQUARED divided by resistance. When you double the
voltage, you also double the amperage (assuming resistance stays the same).
