| Abstract: | The measuring precision of cymometer based on conventional theories is waved according to the frequency change of measured signal.The design of main system of frequency measuring is discussed in detail.The design adopts a lower cost MCU with a method called measuring in the same precision which not only has higher measuring precision but also can keep constant measuring precision on the all frequency region.The experiment shows that cymometer has advantages of wide measurement band,high accuracy,low cost and easy to use. |
