摘要
设计了一种基于FPGA的闭环自动增益控制系统,采样保持部分利用互锁技术采集VCA810输出的第1个有效波峰值电压大小,再经FPGA的AGC控制算法,产生控制电压值,经电压调整后,控制VCA810的输出。对本设计过程中产生的小数,做了变小数为整数的处理,从而提高了精度。
The FPGA-based closed-loop automatic gain control system was designed.Its sample-and-hold unit employs the interlock technology to capture the voltage of the first significant sampling peak from the VCA810,and then to produce a control voltage and have it adjusted through the AGC control algorithm to control VCA810 output.The decimals in this design were converted into an integer to improve the precision.
