| 摘 要： | 回顾了采样抖动的研究进展, 主要针对两种基本采样抖动: 随机抖动和非随机抖动. 每一种抖动均从三种不同的技术形式进行介绍: 实时采样; 等效采样; 非均匀采样. 每一种技术形式均按照三个研究方向予以归纳展示: 采样抖动的影响; 采样抖动的测量与评估; 采样抖动的修正与补偿. 总结归纳了采样抖动研究所涉及的主要理论、方法、技术, 使用的主要信号波形, 采样抖动研究的基本问题, 研究目标和最终目的. 总结归纳出了抖动与噪声的根本区别在于其影响依赖于信号波形的时变性的本质特征.

| Abstract: | Two basic sampling jitters,the random and the nonrandom,are reviewed.Each of them is introduced from three different techniques: real time sampling;equivalent sampling;nonuniform sampling.Each technique is described from three aspects: the influence of sampling jitter,the measurement and evaluation of sampling jitter,the modification and compensation of sampling jitter.Main theories,methods and techniques related with the sampling jitter are discussed in detail.The summarized conclusion is that,the differen... |
