摘要
本文给出了一种利用单片机进行控制的精密测频方法,以及该方法克服测量误差的原理。并对传统的测频方法中存在的精度低的问题进行了简单分析。
A new method controlled by the single-chip to measure frequency precisely is presented in this paper. A theory to overcome measuring errors is also given. This paper makes a simple analysis of the low measuring precision existing in the traditional frequency measuring methods.
