| 摘 要： | 为扩大低频时码接收机的输入动态范围,进行了数字式自动增益控制(AGC)的设计。详细介绍了低频时码接收机数字式自动增益控制的设计方法和实现原理,并进行了计算机仿真。仿真结果表明,该数字式自动增益控制是可行的,相对于没有实行自动增益控制的情况而言,大大增加了接收机的动态范围。

| Abstract: | A design of digital automatic gain control(AGC) in low-frequency time-code receiver is made in order to extend the dynamic range of input signal.The design method and realization principle for the digital automatic gain control in low-frequency time-code receiver are introduced in detail.The simulation is made and the results indicate that this digital AGC is feasible and the dynamic range of the receiver is greatly improved compared with that of the receiver without AGC. |
