通信原理实验箱数字信号源模块的改进设计
|
摘要
物理与电子信息学院目前使用的通信原理实验箱在设计上存在不足,使用中非常容易损坏,严重影响实验教学。基于对信号源的要求,在箱体自带信号源模块的基础上提出改进方案。采用虚拟化仿真软件Multisim 13.0进行软件仿真,论证设计的正确性和简化设计复杂度,利用Altium Desinger设计PCB样品板进行硬件测试,完成设计和安装,设计模块使用的电源是来自实验箱自带的直流稳压电源,在模块的电源部分进行了滤波处理,设计成品用于通信原理课程实验教学中。
Currently, the experimental box of communication principle used by the College of Physics and Electronic Information is deficient in design. It is very easy to damage in use, which affects experimental teaching seriously. Based on the requirement of the signal source in the experiment box, the improvement scheme is putted forward on the basis of the signal source module of the box. To demonstrate the correctness of the design and simplify the design complexity, the virtual simulation software Multisim 13.0 is used to carry out the software simulation. We use the Altium Desinger to design the PCB sample board for hardware test, completing the design and installation. Besides, the power used in the design module comes from the DC regulated power supply from the experimental box. We filtered the power part of the module and the finished products are used in the experiment teaching of communication principle course.
