Equalization-enhanced phase noise induced timing jitter

Optics Letters, 2011
In electronic digital signal processing based optical communication systems, digital equalization for chromatic dispersion interacts with local oscillator phase noise to produce equalization-enhanced phase noise (EEPN). In addition to both phase and intensity noises, EEPN also induces timing jitter to the equalized signal.

Trellis codes for transition jitter noise

IEEE Transactions on Magnetics, 1999
We present a trellis code which reduces the probability that transition jitter will cause one allowed sequence to be decoded as another allowed sequence. This code requires that transition times mod 4 be in the code of a 4-state convolutional encoder. We also exclude adjacent transitions (d=1).

Jitter Noise of Sampled Multitone Signals

IEEE Transactions on Circuits and Systems II: Express Briefs, 2011
Clock jitter degrades the performance of data converters in mixed-signal systems. The sampling operation inherent to analog-to-digital and digital-to-analog (D/A) conversion is inevitably subject to random timing uncertainties. These small timing errors introduce a noise component into the system that degrades the effective resolution of the data ...

A delta-sigma DAC with feedforward jitter-shaper reducing jitter noise

2017 MIXDES - 24th International Conference "Mixed Design of Integrated Circuits and Systems, 2017
This paper present a novel delta-sigma digital-to-analog converter with a jitter shaper that has feedforward passes to reduce the noise caused by clock jitter. Intermodulation between the quantization noise and clock jitter produces wide spectrum noise, which degrades the signal-to-noise ratio (SNR) of the delta-sigma DAC.

Noise induced jitter in differential signaling

2008 58th Electronic Components and Technology Conference, 2008
Differential lines are extensively used in high-speed digital circuits due to their ability to improve signal integrity by rejecting common-mode noise. However noise is injected into differential signals when there are irregularities in the signaling setup.

Maximum likelihood estimator for jitter noise models

IMTC/99. Proceedings of the 16th IEEE Instrumentation and Measurement Technology Conference (Cat. No.99CH36309), 2003
High frequency sampling scopes suffer from both additive noise and time jitter. The classical techniques for identifying the additive noise and time jitter noise are based on linear least squares estimators. This work derives the maximum likelihood estimator and compares it performance with the least squares estimator.

Phase Noise and Jitter

2009
In this chapter we examine variations that occur in the edge locations of the clock signal in a synchronous system. These edge variations are referred to in the time domain as jitter and in the frequency domain as phase noise. We also describe the various mechanisms that can cause these non-idealities and present techniques to analyze their individual ...

Phase Noise and Timing Jitter

2003
Phase noise and timing jitter are closely related terms. Their values can sometimes be derived from each other. Before further analyzing the oscillator phase noise, it is necessary to look closely at the definitions for both terms and understand their relationship.

Jittering Wave-Packet Models for Subsonic Jet Noise

16th AIAA/CEAS Aeroacoustics Conference, 2010
Abstract Three simplified wave-packet models of the coherent structures in subsonic jets are presented. The models comprise convected wave-packets with time-dependent amplitudes and spatial extents. The dependence of the radiated sound on the temporal variations of the amplitude and spatial extent of the modulations are studied separately in the ...
