【摘要】 "电路理论"是电气、电子、信息与控制等学科重要的专业基础课,零输入响应、正弦稳态响应是电路理论教学中不可缺少的内容。通常认为,零输入响应要衰减到零,正弦稳态响应一定是与电源同频率的正弦函数。本文提出,含电容割集的电路或含电感回路的电路,其零输入响应可能存在稳态值,其正弦稳态响应可能存在直流分量,并分别对这两类电路的零输入响应、正弦稳态响应进行了实例分析。更多还原

【Abstract】 Circuit Theory is the fundamental course of many majors such as electrical, electronics, communication and control engineering. Zero-input response and sinusoidal steady-state response are necessary contents in this course. It is generally considered that zero-input response must attenuate to zero and sinusoidal steady-state response must be the same frequency sinusoids as the source. It is proposed that there is possibly steady value in zero-input response and possibly DC component in sinusoidal steady-state response of circuits with capacitance cut-set or inductance loop. This paper provides examples and analysis on the zero-input response and sinusoidal steady-state response for such circuits.更多还原
