摘 要: 本文介绍一种时基电路555上跳沿触发单稳态电路设计方法。首先,对电路的工作原理进行分析并讨论了电路工作参数计算方法。然后,通过仿真和实物实验,验证了该设计方法的正确性。最后,阐明该电路与下跳沿触发单稳态电路相比较的特点。 To develop the application of 555 time-basd ecircuit, this paper recommens a design method with rising edge trigger and monostable circuit. Firstly, the working principle of the circuit is analyzed and the computing methods of the parameters of the circuit are discussed. Secondly, the correctness of the recommend method is veri- fied by simulation and practicality experiment. Finally, the characteristics of the circuit are compared with the fall- ing edge trigger and monostable circuit.
