【Abstract】 By the way of quantifying delay time, an accurate short time interval measurement method can be completed. Based on the method and combined with other techniques, frequency, period, time interval, phase and many other signals can be measured accurately. The paper introduces particularly the theory of this new method and its combination with a high accuracy and fixed gate-time measurement method based on the multiple period synchronization method. The high speed, high accuracy and continuous frequency measurement in wide band is accomplished.更多还原
