| 摘 要： | 在数字选频表或数字扫频仪使用中,由于用户习惯使用转轮来改变频率,所以在新仪器的设计中保留这些用户操作方便的使用习惯,文章介绍了在数字化控制中如何检测转轮转动的方向,如何获得转轮转动的快慢,从而根据转轮的转动速度改变频率变化,达到扫频的良好效果.

| Abstract: | When using digital selective lever meters or digital sweep frequency meters, users are accustomed to alter frequency by rolling wheel, thus in the new design the users' conventional operating custom is retained. This paper introduces how to detect rolling direction of the wheel and achieve good purpose in sweeping frequency. |

| Keywords: | selective lever meter step sweep frequency single chip |
