摘要
本文阐述了一般数字自动增益控制的原理，结合实际，给出了一种基于CPLD的时序、数据处理的数字自动增益控制方案，经课题验证，该方案能够为数字信号处理前端提供稳定中频信号的支持，满足数字接收机的采样需求。
The article tells the principle of common digital AGC control, thus it follows shows a project of digital AGC based in CPLD timing and data processing, for lessons＇ validation, it can provide the stable IF signal for the front digital signal proceeding, also can reach the requirements of sampling of digital receiver.
