摘　　要：文中首先研究了数字中频接收机中的步进式AGC算法,介绍了它的组成。然后通过仿真考察了AGC的性能。仿真结果显示延迟AGC可以基本消除普通AGC的峰值泄漏现象。最后,通过对仿真结果的分析,文中给出了AGC参数调整的方法。The algorithm of a step AGC in digital IF receiver was researched and its components were introduced. The performance of the step AGC algorithm was estimated by simulation. The simulation results show that the peak value could be reduced by delay AGC. Finally, methods of adjusting the AGC parameter were presented.
