摘　　要：针对一般教科书缺乏对基本触发器、单稳态电路及多谐振荡器设计方法的论述问题,从电路存储信号需求出发,研究了基本触发器、单稳态电路及多谐振荡器间的内在联系,发现通过在基本触发器的支路中接入电容,由电容的充放电实现单稳态电路及多谐振荡器,从而提出了基本触发器、单稳态电路及多谐振荡器的统一设计方法,并在课堂上讲授。这不仅有利于学生学习和掌握这3种电路的设计方法,深入理解这3种电路的工作原理,而且可培养学生探索事物本质及其内在联系的能力。Due to the lack of discussion on the design methods of latch, monostable circuit and multivibrator in textbooks, the internal relationship of these three kind circuits was studied from the demand of circuit storage signal. It was found that the monostable circuit and multivibrator can be realized by charging and discharging the capacitor which was connected to the latch, then the design methods of latch, monostable circuit and multivibrator were derived, and they were taught in the university courses. The new approach is conducive to students′ learning on the design of these three circuits, help them to understand the performing principle of these three circuits, and train students′ ability to investigate the essence and internal relationship of circuits.
