| Abstract: | On the basis of brief introduction and analysis of several digital frequency measurement principles and methods, this article expatiates the design of intelligent cymometer, which adopts the technology of equal precision synchronal measurement, ranges from 0. 1Hz to 1MHz, has the highest resolving power of 0. 1Hz. It expounds the principles of measurement, the structure of the system and design of software and hardware, it also analyses the intelligent measurement and systematic errors. The results of the experiments demonstrates that the instrument fulfill the requirements both on the range and the precision of frequency measurement. |
