根据以往的研究和本研究所考虑的文献研究，可以用两种不同的定义来定义抖动，其中一种是数字格式，另一种是模拟。在抖动的模拟定义中，抖动被解释为“相位偏移”或“相位鼻”，它负责不断改变接收和发送信号的定时。当分析诸如时钟信号之类的模拟波形时，特别使用上述定义。

这可以用一个公式来解释：

S（t）= p（t +ϕ（t））（1），其中，S（t）=是指抖动性的信号波形，P（t）=指的是一个波形的性质，ϕ不失真（t）=指相位偏移

为了避免出现抖动，必须连续观察1/0和0/1信号的转换信号。比特流可以传输的数字通信系统中用不同的方式，一种将发送，通过抖动的初始定义的应用，非归零（NRZ）数据流没有任何从时钟导致时钟信号在接收端信号本身的创作。这需要使用CDR电路；从接收机端数据信号中恢复时钟信号的过程称为CDR。

传输数据的数量和速度一直在不断增长，越来越多地支持因特网主干网流量的不受限制的增长，主要是因为电影正在传播，而其他服务用于提供内容。在基础设施和高速通信的需要，导致了越来越多的参考信号的频率高，在输出信号提供稳定的帮助来源的强烈需求（阿斯特拉罕，2006）。

According to the previous research conducted and the literature study that has been considered for the purpose of this study, jitter can be defined with two different definitions where one is in a digital format while the other is an analog. In the analog definition of jitter, jitter is explained to be a “phase offset” or a “phase nose” that is responsible of continually changing the timings of a receiving and transmitting signal. The above definition is particularly used when analyzing any analog waveforms such as clock signals.

This can be explained by a formula that is:

S(t) = P(t + ϕ(t)) (1), where, S(t) = refers to the signal waveform that is jittered in nature, P(t) = refers to a waveform that is undistorted in nature and ϕ(t) = refers the phase offset.

It is necessary that the transition signals of 1/0 & 0/1 signals are continuously observed for any occurrence of jitters. The bit stream can be transmitted within the digital communication system using different ways where one way would be sending, as applied by the initial definition of jitter, Non-Return-to-Zero (NRZ) data streams without any signals from the clock which further results in creation of clock signals at the receiver end itself. This requires the use of CDR circuit; the process involved in recovering clock signals from the receiver end data signals is known as CDR.

Volume and speeds of transmitting data have been continuously and increasingly supporting unrestricted growth in the flow of traffic over the backbone of internet mainly because of the movies being spread and other services for the delivery of content being available. The need for having infrastructure of communication with high speed has resulted in increasing the strong demand for the sources of reference signal with high frequency that help in providing stability in the output signals (Astrahan, 2006).
