전압이득,voltage_gain - 전압,voltage
{
단위: V/V 또는 dB

The voltage gain, $A_v,$ is defined as
$A_v = \frac{v_{\rm out}}{v_{\rm in}}$

gain을 데시벨,decibel(dB)로 나타내면 { dB = 20 log (V/1V) or 20 log (I/1A), dBm = 20 log (V/1mV) or 20 log (I/1mA), dBW = 10 log (P/1W) ?? }
$\left.A_v\right|_{\rm dB} = 20\log\frac{v_{\rm out}}{v_{\rm in}}$
