补充资料：自动增益控制
| 自动增益控制 automatic gain control 使放大电路的增益自动地随信号强度而调整的自动控制方法。实现这种功能的电路简称AGC环。AGC环是闭环电子电路，它可以分成增益受控放大电路和控制电压形成电路两部分。增益受控放大电路位于正向放大通路，其增益随控制电压而改变。控制电压形成电路的基本部件是AGC检波器和低通平滑滤波器，有时也包含门电路和直流放大器等部件。放大电路的输出信号u0 经检波并经滤波器滤除低频调制分量和噪声后，产生用以控制增益受控放大器的电压uc 。当输入信号ui增大时，u0和uc亦随之增大。 uc增大使放大电路的增益下降，从而使输出信号的变化量显著小于输入信号的变化量，达到自动增益控制的目的。放大电路增益的控制方法有：①改变晶体管的直流工作状态，以改变晶体管的电流放大系数β。②在放大器各级间插入电控衰减器。③用电控可变电阻作放大器负载等。AGC电路广泛用于各种接收机、 录音机和测量仪器中，它常被用来使系统的输出电平保持在一定范围内，因而也称自动电平控制； 用于话音放大器或收音机时，称为自动音量控制。 |
