基于FPGA的高精度相位计的设计与实现
摘要
Abstract
Phase meter is the instrument for measuring the phase difference between two signals with same frequency, it is a kind of widely used electronic instrument. This paper fol ows the EDA design flow,using VHDL language to design the logic circuits of phase meter and realizing the phase meter measurement, conversion functions on Cyclone FPGA-based development board.A new method of phase measurement is proposed based on FPGA,and the error sources and accuracy of this method are analyzed. The measure precision of this design reaches 0.1°, and puts forward an improving method for this phase meter.关键词
