摘要
频率的测量,在生产和科研部门中经常使用,同时也是大型系统实时检测的重要组成部分。本频率测量电路是以AT89C51为核心,实现周波频率的测量及使用动态扫描的方法将测量结果显示出来。
The frequency measurement is used frequently in the production and the scientific research department,at the same time it is also the important component of some large-scale systems which take real -time examinations. This electric circuit of frequency measurement is take AT89C51 as the core. It can survey the realization cycle frequency and show the measurement result by using dynamic scan method.
