Power Gain is a measure of the ability of a circuit 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 an important feature in analyzing Power Electronic Systems. Decibels are defined as ten times the logarithm(base 10) of Power Gain. It is also widely used in electronics, signals, and communication.
