摘　　要：本文介绍了一种以Altera Cyclone FPGA对相位差数据进行采集的低频率数字相位仪的设计方法,按照设计要求,从理论上分析了相位仪的精度并进行设计,将FPGA数据采集电路设计成五个模块,并使用Quartus Ⅱ对VHDL语言编写的程序进行了仿真。这种设计方法充分利用了FPGA器件的特性得到较为简单的硬件电路,简化了软件编程。This paper introduces a design method of a low frequency digital phase meter with Altera Cyclone FPGA to collect the phase difference data. According to the design requirements, the precision and design of the phase meter are analyzed theoretically. The FPGA data acquisition circuit is designed into five modules, and the program written in the VHDL language by Quartus II is used. The simulation. This design method makes full use of the characteristics of FPGA devices and gets a relatively simple hardware circuit, which simplifies the software programming.
