| Abstract: | 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. |
