- 提出了一种针对数字电视DVB-C系统QAM解调器自动增益控制模块的设计方案,该设计通过前端AGC模块控制高频头和中频放大器增益,补偿信号衰减,通过解调器内部数字AGC精确调整信号电平。 This paper describes a design of automatic gain control module for QAM demodulator in DVB-C system. In this design, the front AGC module compensates the attenuation of signal by controlling the gain of RF amplifier and the IF amplifier. The signal level is accurately adjusted by means of the internal digital AGC.
