摘要
本系统以单片机为核心，设计用于测量频率、周期、时间间隔的仪器，采用双计数器进行“相关计数”等高精度测量方法实现高低频等精度测量。
A new intelligent frequency meter based on a microcontroller can measure frequency, period and interval. The correlated couner and the synchronize frequency divided by hardware technique are used, we can achieve equal accuracy measurement at not only high frequency but also low frequency so the accuracy is higher.
