| 摘 要： | 讨论了一种具有空间迟滞特性的等间距信号发生器电路的原理,并提出几种具体的设计方案。这些电路可以对传感器的位移方向进行判断,并在位移方向改变时,对等间距信号的输出加上了适当的迟滞。借助于这种电路,可以基本上克服因机械振动引起光码盘抖动失控而导致数据采集系统误动作的问题。

| Abstract: | An equidistant signal generator with spatial lagging property was discussed in this paper. And some practical circuits designa were also proposed. These circuits can detect the moving direction of transducer. When it changes, the output of the equidistant signal can be lagged. With these circuits, the data acquisition system can refrain from the errors led by quivering of optical encoder caused by mechanical vibration. |
