The performance of real time applications such as video and voice streams relies on packet delay jitter. Large delay jitter causes buffer overflow or underflow at the receiver end and the user encounters interrupts. The delay jitter is mainly due to the perturbation of background traffic in the bottleneck router. Fulton and Li 1121 provide an analytical approximation for the tirst-order and sec...

With high bandwidth demand in the telecommunication and networking area, low voltage and low jitter Phase Lock Loop (PLL) is becoming of utmost importance. As the data rate becomes faster, the total jitter budget gets smaller. For instance, an OC-192 transceiver compliant is allowed less than 1ps of total jitter due to random noise (rms jitter) and a maximum of 10ps for the deterministic jitter...

Satellite jitter (SJ) is an important error source that affects the geometric accuracy of high resolution satellite imagery. In this paper, the quantitative relationship between the jitter displacement (image displacement caused by SJ) and relative registration error obtained from parallax images is deduced to be theoretical in detail, and the jitter displacement estimation model is built to es...

One of the factors limiting the performance of continuous-time sigma-delta modulators (CTSDM) is clock jitter. This jitter can be classified as synchronous and accumulated/longterm jitter. A clock that is derived from a phase-lock loop (PLL) contains both types of jitter. In this paper, we present a framework that can be used to obtain the output spectrum in the presence of jitter, either synch...

Today, One of the most important performance measures in the new burst traffic occurs to 3G and 4G systems is the End-to-End jitter. However, in order to study and analyze Jitter ,many works have been devoted to estimate and evaluate this parameter. In this paper, an analytical approximation for jitter is presented. In one node case, we found that the jitter can be approximated by the average a...

In this paper we present results concerning validity of jitter measurement in strongly irregular voice signals (sustained vowels) moderately corrupted by noise. The performance of four tools for voice analysis is compared on synthetic signals as far as fundamental period and jitter estimation are concerned. Synthesised vowels offer the advantage of a perfect control of the amount of jitter put ...

In this paper, we investigate the use of jitter estimation over short time intervals (short-term jitter) for voice pathology detection in the case of running or continuous speech. Short-term jitter estimations are provided by the spectral jitter estimator (SJE), which is based on a mathematical description of the jitter phenomenon. The SJE has been shown to be robust against errors in pitch per...

Jitter is a key performance factor in high-speed digital transmission systems, such as synchronous optical networks/synchronous digital hierarchy (SONET/SDH), optical transport networks (OTN), and 10 Gigabit Ethernet (GE). This paper outlines the differences between telecom and datacom jitter standards and describes the various jitter applications for compliance testing of 10 G small form-facto...
