Stands for decibel gain.
Power gain, in decibels (dB), is defined by the 10 log rule as follows:
where Pin and Pout are the input and output powers respectively.
A similar calculation can be done using a natural logarithm instead of a decimal logarithm, and without the factor of 10, resulting in nepers instead of decibels:
db X 10 db gain x 10 9 db gain x 8 8 db gain x 6 7 db gain x 5 6 db gain x 4 5 db gain x 3 4 db gain x 2.5 3 db gain x 2.0 2 db gain x 1.5
