Measuring the Jitter of Clock SignalIn the digital transmission system, jitter is a very important and less well known phenomenon.With the clock frequency in digital system becomes higher and higher, jitter is having moreeffect on the digital transmission system. Thus it is very important to find a way to measure jitter.This paper introduces the concept of jitter and the effect it has on the digital system. It comparesthe analog and digital methods to measure jitter. The corresponding international standard (ITU)on jitter is also introduced. It then proposed a scheme to measure the jitter of a fixed frequency(2.048MHz) PLL clock signal. This scheme uses digital method with DSP as the core. It alsoemploys CPLD in its implementation. This method has the advantage of being simple but at thesame time easy to implement.
