【Abstract】 A module design on high precision time interval measurement is proposed in this paper. The system is controlled by single-chip microcomputer. Based on pulse counting principle, the high precision time interval can be obtained by measuring the number of the high-frequency reference clock through it. The module is simple in structure and easy to implement, and it has advantages of low cost and high accuracy. It can be widely used in the field of time measurement.更多还原
