timing sampling

This board uses two chips, six channels A/ D converter and phase locking synchronous technology for collecting three-phase voltage and current signals in timing and equal-time cycle sampling ways, and the gained data make more reasonable for power quality norm analysis.

并采用了两片六通道高速A/D转换器和运用了锁相同步技术，对三相电压和电流信号能进行定时采样和等间隔采样，这样得到的数据对于下一步电能质量指标进行分析更为合理。

Reversal current chronopotentiometry have to restrict sampling interval. To solve this problem, timing control is applied in electric relay. Timer control which is included in Delphi is used in the program. Program of controlling electric relay is executed every 4 seconds.

为了解决使用电流反向法必须要限制采样间隔的问题，我们对继电器实施定时控制，在编程中使用Delphi中的时钟控件（timer），每4秒钟执行一次程序。

Following the introduction of the basic principle of OFDM, some nonideal effects on the performance of OFDM systems are discussed, such as carrier frequency offset, symbol timing offset and sampling clock deviation.

本文在简要介绍了OFDM的基本原理、关键技术的基础上，针对同步问题进行了深入研究。首先分析了同步偏差中的频率偏差、符号定时偏差及采样时钟偏差对系统性能的影响。

The influence of timing jitter and amplitude fluctuation of the sampling pulses is also investigated.

同时我们还研究了采样光脉冲时间抖动和幅度抖动对光性能监测系统的影响。

Timing adjustment in a digital modem must be performed by interpolation if sampling is not synchronized to the data symbols.

在数字调制解调器中，如果采样率与数据符号不同步，则必须通过插值对定时进行调整。
