摘要
位于接收机前端的选频放大模块是模拟通信系统中非常重要的一环,但它的分析又较为复杂。为了提高学生学习调谐放大器的效果,基于MATLAB软件工具,运用图形可视化工具——图形用户界面(Graphic Userinterface,GUI)设计了界面简洁、使用方便的调谐放大器仿真平台,使用时只需要输入谐振回路的相关参数,就可以得到单调谐、双调谐、多级单调谐的通频带与幅频特性等参数。该平台具有图文清晰,操作简单,参数调节灵活等特点,方便学生更加快速地掌握调谐放大器相关知识。
In the analog communication system,the frequency-selective amplification module at the front end of the receiver is a very important part,but its analysis is relatively complex.In order to improve the learning effect of students on tuned amplifiers,a simulation platform that has a simple interface and is easy to use for tuned amplifiers is designed by the Graphical User Interface(GUI)based on MATLAB,which only needs to input the relevant pa-rameters of the resonance circuit to obtain parameters such as single-tuned,double-tuned and multi-level single-tuned passbands and amplitude-frequency characteristics.This platform has the characteristics of clear graphics and texts,simple operation and flexible parameter adjustment,which is convenient for students to quickly master the rel-evant knowledge of tuned amplifiers.
