WebConverting a power gain ratio to dBs is calculated by multiplying the log of the ratio by 10: Where P 1 is the power at mid band and P 2 is the power being measured. Note: When using this formula in a calculator the use of brackets is important, so that 10 x the log of (P 1 /P 2) is used, rather than 10 x the log of P 1, divided by P 2. In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port.
