一种改进的多周期测量法

An Improved Multi—period Method of Measuring Frequency

针对洲频法不宜测低频信号,测周法不宜测高频信号,本文提出一种改进的多周期测量法,它的测量精度仅取决于所预选的闸门时间,本文所提方法原理简单,非常适用于智能频率计或其它需要测量信号频率(或周期)的智能仪器。

An improved multi-period method of measuring frequency is given in this paper. By using it. the measurement precision is only determined by the gate time selected beforehand. An example is also included. The method is simple, easy to use, and applicable for every inteligent instrument which needs to measure signal frequencies (or periods).
