根据等精度测频原理， 给出了采用C8051F041单片机为主控芯片的高精度数字频率
计的设计方法。 该方法将待测频率信号经过整形放大后输入单片机， 然后由单片机控制内部
计数器分别对待测信号和标准信号同时计数， 再经运算处理得到测量结果， 并由LCD实时显
示， 同时通过RS232串口传至上位机进行记录分析。 该设计方法与传统测频系统相比， 具有
测频精度高， 速度快， 范围宽等优点-Equal precision frequency measurement principle, given the frequency of using the C8051F041 microcontroller for high-precision digital controller chips
Total design method. The method to test frequency signal after the amplification of the plastic input single-chip, and then controlled by the microcontroller internal
Counter and treat them separately at the same time count of the measured signal and the standard signal, the operation processing the measurement results by the LCD in real time significantly
Said record transmitted to the host computer through the RS232 serial. The design method compared with the conventional frequency measurement system,
Frequency measurement precision, high speed, wide range
