摘要
AGC系统在接收机系统中得到广泛应用.传统AGC一般都是反馈式AGC,不能实现本脉冲控制本脉冲,因此提出了数字瞬时自动增益控制(DIAGC).DIAGC的实现主要通过延迟线的作用来消除产生增益控制量所消耗的时间,控制量在FPGA中查表得出.通过调试可以看到达到了很好的控制效果.
The AGC (automatic gain control) system has widespread application in the receiver system. Generally, traditional AGC is feedback AGC, whose pulse cannot control itself, so a digital instantaneous automatic gains control system (DIAGC) is proposed. The time which is produced the gain control is eliminated by using the delay line. The gain control can be obtained by looking up the table from FPGA. It has proved that the control effect works well by debugging.
