设计的是一种基于ARM的自反馈程控放大器，它由ARM主控模块、放大模块、滤波模块、电源模块、键盘和液晶显示模块构成。以ARM1138作为主控芯片，通过对输出信号进行数据采集及处理，实现放大器增益校正与闭环控制，达到精确程控放大器增益和实时显示的目的(Design is a programmable ARM-based self-feedback amplifier, which consists of ARM control module, amplifier modules, filter modules, power modules, keyboard and LCD display modules. To ARM1138 as the master chip, the output signal by data acquisition and processing, calibration and closed-loop amplifier gain control, programmable amplifier gain to achieve accurate and real-time display purposes)
