In this case the card is set to AutoSync, and receives an ADAT signal with very low jitter (below 1 ns).

在这个例子里声卡被设置成了 AutoSync（一种自动同步技术，如果声卡连接了外部设备的话，声卡会自动把时钟切换成外部时钟），声卡接收到了一个具有极低 jitter（小于 1 ns）的 ADAT 信号。

With the obtained model of the power spectrum, we have theoretically analyzed the contribution of all the amplitude noise, timing jitter and pulse width jitter to the total noise power spectrum. The simulated results show that while the product of pulse width and angular frequency is larger than 1, the pulse width jitter will contribute an amount of noise to the total noise power.

利用得到的模型，理论分析了激光输出光脉冲各个噪声项对总噪声功率谱的贡献情况，并数值模拟了输出脉冲功率谱，结果表明在脉冲宽度角频率积大于1的情况下，脉冲宽度抖动对总噪声功率谱有很大的贡献。

A simple model of jitter-error audibility has shown that a DAC can tolerate white jitter noise of up to 180ps, but that even lower levels of sinusoidal jitter may be audible.

一个简单的模式抖动误差可听度表明，一个DAC可以承受高达180ps抖动白噪声，但正弦抖动甚至更低的水平可能会听见的。

We now have to make some assumptions about the characteristic of the jitter to proceed. One assumption that seems to work is that the jitter amplitude has a Gaussiandistribution. For a jitter waveform that has a Gaussian distribution, there is a point on the Gaussian jitter distribution curve that reflects the RMS value of jitter for Gaussian distribution waveforms, just as with the wave.

一个可行的假定是Jitter幅度具有高斯发布，对于有高斯发布的Jitter波形，高斯Jitter分布曲线上有一点反映了Jitter在高斯分布波形下的RMS值，这点称为"1-sigma值，标准分布"或者"RMS Jitter"值。

First, as already mentioned, the assumption is that the jitter has a Gaussian distribution.

首先，向前面提到的那样，要假定Jitter具有高斯发布。

A new jitter measurement method is developed,which is based on equivalent sampling.

提出了关于时钟jitter的一种新的测量方法。

Yet another way to measure the effects of jitter is measure its power level.

另一种评估Jitter影响的方法就是测量它的功率等级。

Its highly efficient jitter suppression enables ADI-648, HDSP 9632 and HDSP MADI to refresh and clean up any clock signal, and to provide the clock signal as reference clock at the word clock output.

它具有非常有效的 jitter 抑制能力，能让 ADI-648、HDSP 9632 和 HDSP MADI（这几个都是具备了 SteadyClock 技术的产品）把任何时钟信号都&清洗干净&，并且提供了等同于字时钟输出的时钟信号。

Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.

由于信元抖动的复杂性，非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能，以及在目的节点的源定时恢复问题作了较为全面的研究。首先，文中描述了CBR业务流的信元抖动，并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后，采用了精确的数学模型和分析方法，有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法，在性能分析中，我们成功地完成了CBR业务流信元抖动的功率谱分析，使得不但可以从频域定性地认识信元抖动的能量分布特性，而且还可以定量地求出信元抖动的均方根值(rms：root-mean-square)，以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中，我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流，并基于这一模型进行了CBR业务流中间节点的初步排队分析。
