摘要
分析了采用计数器测量信号频率的方法中存在的问题,提出了一种用单片机控制、测量误差与被测信号无关、能够达到很高精度的测频方法。
The weak points in common method of measuring signal frequency by electronic counter is discussed in this paper. It presented a design of measuring method which is controlled by microprocessor. The measuring deviation is not related to the signal measurment and it can reach very high pricision.
