摘　　要：由于机械触点的弹性作用,按键开关存在一个抖动的特性,如果不作处理这个抖动会给系统带来一些不稳定的因素,甚至是错误的结果,为了不产生这种现象就必须采取相应的消抖措施。本文就消抖技术作相关介绍,并举一实例作为消抖技术扩展应用的说明。Due to the flexibility of the role of mechanical contact,button switch are the characteristics of a jitter,if not treated the jitter will bring some unstable factors system,even wrong results,in order not to cause this phenomenon must take corresponding jitter elimination measures.In this paper,the elimination of shaking technology for the relevant introduction,both as an example of an example of the application of the technology to eliminate chattering.
