Answer:

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 often expressed using the logarithmic decibel (dB) units ("dB gain").
