Circuit Analysis
电路分析是电气工程专业的入门核心课程，系统讲授集总参数电路的基本理论与分析方法。课程内容包括电路元件特性、基尔霍夫定律、节点电压法与网孔电流法、戴维南与诺顿定理、一阶与二阶动态电路的时域分析、正弦稳态交流电路的相量分析及频率响应。通过本课程学习，学生能够建立电路模型并熟练分析直流与交流电路，为后续电子技术、信号与系统等课程奠定理论基础。
Circuit Analysis is the foundational core course for Electrical Engineering majors, systematically teaching the basic theory and methods of lumped-parameter circuits. Topics include circuit element characteristics, Kirchhoff's laws, nodal and mesh analysis, Thevenin and Norton theorems, transient analysis of first- and second-order dynamic circuits, phasor analysis of sinusoidal steady-state AC circuits, and frequency response. Students learn to model and analyze DC and AC circuits, laying the theoretical foundation for subsequent courses in electronics and signals.
学生使用 Multisim 或 LTspice 搭建 RLC 串联与并联二阶电路，分别设置过阻尼、临界阻尼与欠阻尼三种状态，测量电容电压与电感电流的暂态响应波形。要求撰写报告分析元件参数对响应的影响，并通过参数优化使系统在指定时间内达到稳态，提交仿真文件与设计说明书。
Students use Multisim or LTspice to build RLC series and parallel second-order circuits, configuring over-damped, critically damped, and under-damped conditions, and measuring transient response waveforms of capacitor voltage and inductor current. The report should analyze the effect of component parameters on responses and optimize parameters to reach steady state within a specified time. Submit simulation files and a design document.
