| Abstract: | A new phase measurement solution is proposed, thus to improve the stability and precision of phase measurement system. This solution, based on high master frequency microprocessor C8051F410, by using shift-phase technology, and by collecting two same frequency signals of different phase in double-channel, which is then processed by the DSP kernel of C8051F410, precisely measures the phase-difference value. Experiment indicates that this system is of high stability and precision, and is simple and practical,... |
