| Abstract: | A frequency meter adopting microcontroller as the core control device was designed and implemented based on the equal precision synchronal measurement.On the basis of brief introduction and analysis of this system working principle,the measurement errors of the system were analyzed.The experimental results demonstrate that the designed frequency meter can realize the frequency measurement ranging from 0.1 Hz to 30 MHz.The measurement accuracy is kept below 0.01%,which is not changed with the measurable frequency. |
