automatic gain control

基本解释

Wideband amplifier, realized by the technology of automatic gain control (AGC), is used widely in radar system and other correlative electronic fields.
采用自动增益控制（AGC）技术实现的宽频带放大器在雷达系统及其他相关电子领域有着广泛的应用。
An automatic gain control circuit, its method, and demodulation apparatus capable of high-speed accurate level capture and preventing generation of an error and system destruction.
一种自动增益控制电路、其方法以及解调装置，能够高速精确地获取电平，防止产生误差和系统破坏。
Upon reception of a burst detection start trigger signal, a gain control signal is output to an automatic gain control amplifier (201) so as to perform amplification with a maximum value.
当接收到短脉冲检测开始触发信号时，向自动增益控制放大器（201）输出一个增益控制信号，以便用最大值进行放大。

It also has smart sound, an automatic gain control thing, which automatically adjusts the volume to the optimal level.
