【摘要】 论文主要分析了在"电路"与"信号与系统"课程中,相量法与傅里叶变换法两者之间的联系与区别。相量法和正弦稳态电路的分析、频率响应及零状态响应分析分别是各自课程中的重点及难点,对后续课程起着关键性的作用。文中通过实际例子详细分析了相量法与傅里叶变换法在求解频率响应方面的一致性,特别重点讨论了在求解系统零状态响应方面,学生容易误解而许多教科书也没有具体讲解到的两者之间的区别。更多还原

【Abstract】 In this paper,the relationship and differences are mainly analyzed between phasor method and Fourier transform method in the "Circuit" and "Signals and Systems" courses.Phasor method,sine steady-state circuit analysis,frequency response and zero-state response analysis not only are focus and difficulties of their subjects respectively,but also play a key role in the follow-up courses.Based on the specific examples of teaching practice,the unity of phasor method and Fourier transform method in solving the frequency response is discussed,and the difference of them in analyzing zero-state response is researched in detail which many students misunderstood easily and not be explained concretely on many textbooks.更多还原
