摘要
通过分析机械开关产生抖动的原因和可能造成的影响,指出了设计机械开关消抖电路的必要性,给出了三种硬件消抖电路的设计方法,电路简单,工作稳定可靠,可在数字电路设计中广泛使用。
The paper analyzes the reason why mechanical switch can cause jitter and the probably effect,points out the necessity of designing jitter proof circuits for mechanical switch,presents three kinds of hardware design methods of jitter proof circuits.The circuits are simple and reliable,and can be wildly used in digital circuit design.
