高精度时间间隔测量方法的研究

为了解决传统时间间隔测量方法中测量精度高与测量时间长之间的矛盾,本文提出相位时间间隔测量方法,将待测脉冲的时间转换为与之对应的相位,再通过运算就可以得到待测脉冲的时间值.经理论分析和计算机实验仿真,表明此方法能够解决测量精度高与测量时间长之间的矛盾,同时克服了传统时间间隔测量方法的测量原理误差.而且合理选择模数转换器的...

Precision Time Interval Measurement Method

In order to solve the conflict between high precision with measurement of long time in traditional methods of measurement interval,this paper proposes the measurement way of the time interval measurement phase which uses the time of the pulse under test converted to the corresponding phase,and then tested by computing pulse time value.The theoretical analysis and computer simulation experiments show that this method can solve the conflict between the high accuracy with long measuring time in the time interv...
