一种基于滑动滤波的数字AGC应用
pplication of DAGC based on flip-filter
阐述了一种基于滑动滤波的数字自动增益控制(DAGC)的实现方法,采用数字下变频(DDC)后数据的模值作为样本数据,运用滑动滤波算法,计算反馈控制量(功率衰减量),作用于中频接收机数控衰减器,控制接收通道增益,使DDC后数据模值稳定在期望值。由于采用了滑动滤波算法,所以便于工程实现,且在指标范围内实现效率高。
method of digital automatic gain control(DAGC), based on slip filter. The modules of the DDC date is sampled, and used as input of the slip filter. The result of the filter's output controls the attenuator that controlling the receive channel's gain. Using this method, the amplitude of the DDC's output is stabilized at a desired value which can be set manually. Because of using the slip filter, it is easy for project implementation, and is more efficient in the restrict of quato.
