摘要
阐述了一种基于FPGA的数字相位检测电路的设计方案。电路还具数字频率测量功能,由于在频率测量电路中采用了量程自动转换功能,因此具有测量范围大、精度高、稳定性好等优点,实用性较强。
This paper describes a phase-meter based on FPGA. As the automatic measuring range is designed in the circuit, it gets the advantage such as high precision, good stability with a small volume. Based on these advantages, this design has a great meaning in practices.
