摘要
分析了由555型定时器构成的一种多谐振荡器产生矩形波的过程,给出了波形持续时间、间隔时间及周期的表达式,推论出此种振荡器能产生方波的结论,这个结论与实验结果一致。
In this paper, the process of producing rectangular waves in a astable multivibrator with a 555 timer is discussed. The expressions of duration,interval and cycle of the wave are given.The conclusion that the astable multivibrator can produce square waves is inferred,and it is coincident with the result of test.
