摘要
文章介绍了一种基于DSP的宽带直流放大器,该装置的信号放大由可控增益运算放大器AD603来完成。同时还采用DSP和AD558增益控制电路实现增益预置并显示,带宽达50MHz,并且增益在0~60 DB连续可调。
This paper introduced a DSP-based DC broadband amplifier. The device＇s amplification is achieved by the gain-controlled amplifier AD603. And using DSP and the AD558 gain control circuit gain preset and display, broadband is 50MHz,preset range is 0-60dBo
