摘　　要：数字移相触发集成电路以其优越的性能在市场的占有率逐步上升 ,但由于应用的现场环境比较差 ,工业电网输入的同步信号抖动 ,波形畸变 ,严重影响设备的正常运转。详细讨论了输入噪声导致的危害和解决的途径 ,给出了解决方法的基本思想、具体电路和实验结果。The market possession of digital phase shift IC is increasing gradually due to its predominant performance. In practical terms, the bad circumstance, such as the unstable frequency of industrial power net, the aberrant waves, affect the normal operation of equipment seriously. The paper analyzes the results of input noise in detail and gives the resolving method. It affords the algorithm, circuits and experiment results. The method is of engineering practical value.
