一、抗干扰的必要性随着半导体器件的发展和运用,随着电路功能的不断完善和不断提高,抗干扰问题愈来愈提到议事日程上来了。有些革新或试制的脉冲数字控制设备:如数控线切割机、数控车床、电子计算机、晶体管脉冲电源等,在总调时总是费一番周折。干扰问题使调试速度大大减慢下来。 First, the necessity of anti-interference With the development and use of semiconductor devices, with the continuous improvement of the circuit function and continue to raise anti-interference issues more and more mentioned on the agenda up. Some innovations or trial of pulse digital control equipment: such as CNC WEDM, CNC lathes, computer, transistor pulse power, etc., in the total transfer is always some twists and turns. Interference problems slow down the debugging speed.
