摘要
给出两种基于计数器的数字频率计测量量程自动切换的实现方案,分析两者在切换速度和稳定性方面的异同点,并在FPGA开发装置上得以验证,具有一定的实用参考价值。
Two methods on automatic switching measurement range of the counter based digital frequency meter are proposed,and at the same time,an analysis of and a comparison between the two methods in terms of the switching speed and stability are given.The proposed methods are implemented and verified using FPGA device and it shows their considerable value in practical utility.
