【Abstract】 The principle and circuits of ring mono-stable oscillator(RMO)were proposed.The RMO was emulated by using EDA software Multisim8.The application of RMO is introduced.And the temporary stability time,which was depended on the timing element RC of monostable multivibrator,is discussed.According to the timing diagram of traffic lights,the real circuits of one ring mono-stable oscillator with control signal are installed and debugged.更多还原
