资料介绍

周期信号的傅里叶分解与合成实验是大学物理实验课的典型内容。为了提升学生对周期电信号傅里叶分析实验的学习效果,增强学生学习的积极性,介绍采用Multisim对周期信号傅里叶分解与合成进行电路仿真的实验方法。在简介了实验的基本原理后,给出了在Multisim平台上对电信号傅里叶分解与合成进行搭建的电路图,通过调节仿真电路里一些参数来运行仿真功能,模拟出了所需要的电信号的电压波形和合成信号的李萨如图形,并且还对电脑的仿真结果进行了必要的对比分析。研究表明在大学物理电路类的实验教学中应用Multisim能培养学生电路分析和设计的自主学习能力。

Fourier progressional dissolution and composition of periodic electrical signals is a typical example of the telecommunications engineering directon for college physics expermental teaching.In order to improve the efficiency on students' learning frequency spectrum analysis of periodic electrical signals and to stimulate students' interest,the simulation method of RLC circuit and composition circuit by Multisim was introduced.The fundental principles of experiment was given.The simulation circuit was built on Multisim and simulation results were obtained.It shows that the application of Multisim in college physics expermental teaching is feasible and Multisim is helpful to improve students' self-learning ability in college physics expermental teaching.
