| Abstract: | The measurement principle and circuits for measuring the phase difference of two sine signals based on AT89C52 single-chip computer are presented,and the reason which causes the difference is analyzed.The measurement method gives a correct and stable measurement and aphase difference provieded is independent of the signal frequency to be measured,counting signal and clock frequency. |
