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.

Famous quotes containing the word gain:
“Well: what we gain by science is, after all, sadness, as the Preacher saith. The more we know of the laws & nature of the Universe the more ghastly a business we perceive it all to be—& the non-necessity of it.”
—Thomas Hardy (1840–1928)
“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)
“This dog and man at first were friends;
But when a pique began,
The dog, to gain some private ends,
Went mad and bit the man.”
—Oliver Goldsmith (1730?–1774)
