摘要
甚低频天线由于带宽窄,需要进行阻抗匹配,才能保证甚低频发信系统工作在最佳状态。简述了利用拉普拉斯变换、复数运算等数学方法对一种二阶T形调谐网络进行分析,求出调谐在时域和频域上的仿真数据,得到元件的取值范围和参数选择,从而为调谐电路的设计和元器件选型提供了参考依据,对于此类电路的设计以及相关器件的动态响应检测具有良好的指导意义。
Due to its narrow bandwidth,very low frequency antennas require impedance matching to ensure optimal operation of the very low frequency transmission system.This paper briefly describes the use of Laplace transform,complex operations and other mathematical methods to analyze a second-order T-shaped tuning network,to find out the simulation data of the tuning in the time and frequency domains,and to obtain the range of component values and parameter selection,so as to provide a reference for the design of tuning circuits and component selection,which has a good guiding significance for the design of such circuits and the dynamic response detection of related devices.
