摘要
针对传统测频原理的频率计的测量精度随被测信号频率的下降而降低,在实用中有较大的局限性,在对等精度测量原理和测量误差进行详尽介绍和分析的基础上,介绍了基于单片机的等精度频率计的系统构成和工作原理,以及系统的硬、软件设计。
The measuring precision of frequency meter based on traditional frequency measuring principle lowers with the descent of the measured frequency ,so there are great limitations in practical application. According to the analysis of equal precision frequency measuring principle and measuring error, this paper introduced the system constituents and principle of equal precision frequency meter based on microcontroller. The system designs about hardware and software were also presented in detail.
