利用通用计数器和距离计数器的相同工作原理,制作一个满足测距精度要求的时标,与通用计数器配合使用,通用计数器便可代替距离计数器工作。
Using the same working principle of universal counter and distance counter, a time scale that meets the requirements of ranging accuracy is made. When used with a universal counter, the universal counter can replace the distance counter.
