Out of these indicators, one had been used for the evaluation of stability found in the waveforms of output signal, referred to as jitter. When considered for expressing stability in the crystal oscillator of high frequency, jitter helps in indicating a variation or deviation in the duration of wave forms during process of transmission for a digital signal.
Since recent times, it has been found that IEEE has been working on a new standard, P2414 Standard for Phase Noise and Jitter. The key purpose of this standard is focused on facilitation of precise and accurate communication that have concerns with phase noise and jitter, along with the methods used for its measurement (Haskell and Morley, 2004). Due to the broad scope of applying these types of terms in the industries of electronics like industries of telecommunication, computer, and instruments for measurement, presenting methods for measuring these, and development of unambiguous definitions are relevant for communication amongst consumers, users and manufacturers.
There is an extremely broad application of the terms phase noise and jitter within the industries of electronics. There has been generation of a lot of literature for dealing with these. There are a number of misconceptions regarding what can exactly be referred to as jitter as there are huge variations in the definition being highly dependent on the particular application (Haskell and Morley, 2004). As a matter of fact, there is no denial in the fact that there is not a single, particular, universally approved and comprehensive specification that defines phase noise, wander and jitter.
Presence of jitter can always be found in networks, systems and devices to a particular degree. For ensuring the interoperability amongst the devices and minimizing the degradation of signal because of the accumulation of jitter in long miles, it is relevant that limits have been set over the highest degree of jitter.
