摘要
高电平调幅电路是无线发射机中常用的电路。在简要介绍高电平调幅电路特点的基础上,分析了利用Multisim 10.0仿真软件对高电平调幅电路进行构建和调制波形仿真的方法。仿真表明,基极调幅电路比集电极调幅电路更灵敏,但集电极调幅电路效率较高,而基极-集电极调幅电路则可以获得较深的调幅度。
High level AM circuit was frequently used in transmitter.This paper introduced its characteristic,it also analyzed the methods with which the circuit was made up and simulated by the help of Multisim 10.0 simulation software.we can better understand that base AM is more sensitive than collector AM,but the efficiency of collector AM is more high than base AM, base-collector AM circuit is easier to attain the bigger amplitude cofficient.
