RESEARCH AND REALIZATION OF PHASE MEASUREMENT BASED ON CPLD

Wang Chun-he

Abstract

The precision and anti-interference ability of the traditional phase measuring means cannot satisfy the further requirement in many situations. The comprehensive technology involving CPLD and MCU is adopted. It uses CPLD to carry out measurement of phase and frequency. MCU accomplish data processing and display. The precision is high. The result of measurement can show through LCD.The system has good man-machine interface.
