| Abstract: | The principle of frequency measuring based on single chip computer and case of metrical error is analyzed in the paper. The methods for frequency measurement are introduced, and the idea about how to design the hardware and software of the frequency measurement system is presented. The gateway of frequency measuring is controlled by hardware rather then software, which makes frequency measuring highly precise, convenient, agile and reliable. |
