本文从论述信标自频控系统的特点出发,提出了组成此系统应注意的几个要点:自成一路;必须有自动增益控制系统;在中放级实施选通;采用等待式的工作方式;尽可能高的开环增益,并给出了系统主要组成部分的具体电原理图。最后并对此系统的精度和稳定度作了分析。
In this paper, the characteristics of beacon self-frequency control system are discussed, and several key points that should be paid attention to in forming this system are put forward: self-contained; automatic gain control system; strobing in middle level; standby mode ; Open loop gain as high as possible, and gives the specific electrical schematic diagram of the main components of the system. Finally, the accuracy and stability of the system are analyzed.
