Gain
In electronics, gain is a measure of the ability of a circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output. It is usually defined as the mean ratio of the signal output of a system to the signal input of the same system. It may also be defined on a logarithmic scale, in terms of the decimal logarithm of the same ratio ("dB gain"). A gain greater than one (zero dB), that is, amplification, is the defining property of an active component or circuit, while a passive circuit will have a gain of less than one.

““What have I gained?”
“Experience,” said Holmes, laughing. “Indirectly it may be of value, you know; you have only to put it into words to gain the reputation of being excellent company for the remainder of your existence.””

“Face your own ambivalence about letting go and you will be better able to help you children cope with their own feelings. The insight you gain through your own acceptance of change will bolster your confidence and make you a stronger college parent. The confidence you develop will be evident to your child, who will be able to move away from you without fear.”
—Norman Goddam (20th century)
“I find myself ... hoping a total end of all the unhappy divisions of mankind by party-spirit, which at best is but the madness of many for the gain of a few.”
