摘要： A digital time interpolation system and method for quantizing the time-difference between two digital signals. The present invention measures the time-difference between consecutive zero crossings of a user signal and a reference oscillator (316). The present invention outputs interpolator data, which represents this time-difference in digital form. The present invention includes a quadrature hybrid (305), a synchronizer (304), track-and-holds (T&Hs) (306), analog-to-digital converters (ADC) (308), an encoding circuit (312), and a boundary detector (310). The present invention also includes a system for deskewing the recorded coarse time count and the fine time value. According to the present invention, the reference oscillator (316) is a continuous, two-phase signal having a unique pair of output values at any given instant of its period. By using this reference oscillator (316), the present invention accelerates conversion. The present invention uses a novel boundary detection scheme. By using this boundary detection scheme, the present invention avoids the timing errors which are traditionally introduced by measuring synchronizer outputs directly.

摘要翻译：一种用于量化两个数字信号之间的时间差的数字时间插值系统和方法。本发明测量用户信号和参考振荡器的连续过零点之间的时差（316）。本发明以数字形式输出表示该时差的内插器数据。本发明包括正交混合（305），同步器（304），跟踪保持（T＆Hs）（306），模数转换器（ADC）（308），编码电路（312）和边界检测器（310）。本发明还包括用于对所记录的粗略时间计数和精细时间值进行偏斜校正的系统。根据本发明，参考振荡器（316）是在其周期的任何给定时刻具有唯一的一对输出值的连续的两相信号。通过使用该参考振荡器（316），本发明加速了转换。本发明使用新的边界检测方案。通过使用该边界检测方案，本发明避免了通过直接测量同步器输出而传统引入的定时误差。
