摘要
为了改善工业控制中对频率计的测量精度不高和测量带宽不大的问题,依据等精度测量技术,利用单片机STM32F103VET6、FPGA及自增益控制电路(AGC)设计了一款数字频率计,该频率计可以测量信号频率、周期、时间间隔以及占空比等参数.经实测表明,该频率计具有测量精度高、测量带宽大等优点,具有良好的实用价值.
In order to improve low accuracy and small bandwidth of frequency meter in the industrial control, by using equal precision measurement method, a digital frequency meter was designed based on STM32F103VET6, FPGA and automatic gain control （AGC） circuit. The digital frequency meter can measure the parameters such as signal frequency, cycle, time interval, and duty cycle. The test result shows that the frequency meter has high accuracy and big bandwidth, so it has good practical value.
