资料介绍

在传统实验与教学中,由于混频电路性能分析过程复杂和实验操作者主观因素,导致数据读取存在误差,严重影响实验的效率以及学生对电路关键知识的掌握。通过建立LabVIEW与Multisim的联合自动化仿真分析平台,利用Multisim的快速电路分析功能以及LabVIEW强大的数据采集分析功能,为学生构建了一个高效、准确且直观的自动化实验平台,为高校实验教学方法提供新的思路。以MC1496混频电路为例,利用自动化仿真平台实现MC1496混频电路动态范围的快速、准确分析,并在获取混频输出信号基础上,通过编程直接在虚拟实验界面中给出混频增益,通过直观的图形与数据展示混频电路的关键性能指标,大大提高了实验的效率与准确性。

In the traditional experimental and teaching process, the complexity of the mixed circuit performance analysis and the subjective factors of experimental operators may lead to errors in data reading, it influences the efficiency of the experiment and the mastery of the knowledge of circuit knowledge for students. A joint automation simulation platform is established. By using the circuit analysis function of Multisim and the data acquisition function of LabVIEW, students can complete efficient, accurate and intuitive mixer circuit automatic experiments on the platform. It provides a new idea for colleges and universities in experimental teaching. Taking MC1496 mixer as an example, a fast and accurate analysis of the dynamic range of MC1496 mixer is realized by using the simulation platform. On the basis of obtaining the mixed output signal, the gain of mixing is given directly in the virtual experiment interface through programming. The key performance indicators of the mixer circuit are displayed by the intuitive graphics and data. The efficiency and accuracy of the experiment are greatly improved.
