摘要
依据频率参数的电子测量理论，提出了一种准等精度的多周期同步测频法，并利用MCS-51系列单片机进行了实现．结果表明，该方法可充分地发挥单片机资源，使测频误差、测频范围、测频速度等均达到了高要求，是高精度测频的有效方案．
The method for multi-period synchronism of quasi-accuracy is put forward andrealized with single chip computer of MCS - 51 series. The m ethod fully developed the resourcesand functions of the single chip computer, and the questions of measuring frequency is discussedsuch as measuring error, measuring lidrits and measuring rate.
