增益 Gain (electronics)（重定向自Voltage gain）
增益在电子学上，通常为一个系统的信号输出与信号输入的比率。如5倍的增益，即是指系统令电压或功率增加了5倍。增益主要应用于放大电路中。

Gain (electronics) 增益（重定向自Voltage gain）
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 usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the logarithmic decibel (dB) units ("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. |
