A new time-digital convert circuit based on digital delay line

提出了一种基于数字延迟线的时间数码变换方法,该电路具有精度和稳定性高,扩展性强的优点。在与传统计数式时间数码变换方法结合使用后,在使用低频自激振荡器的情况下,可以对较大动态范围的脉冲宽度进行测量,实现了较小的时间道宽和较高的测量精度。

An introduction of a new method of time-digital convert circuit based on digital delay line is given. High precision and good reliability can be realized when it is combined with traditional counting convert method in the measurement of large scale pulse width and low frequency self-excitation oscillator.
