| Constant Bit Rate (CBR) traac is expected to be a major source of traac in high-speed networks. Such sources may have stringent delay and loss requirements and in many cases, they should be delivered exactly as they were generated. A simple delay priority scheme will bound the cell delay and jitter for CBR streams, so that in the network switches, CBR traac will only compete with other CBR tr...

In this paper, a nontrivial sampling clock imperfection analysis is presented for Synthetic Aperture Interferometric Radiometers (SAIR). Sampling clock determines the edges at which analog radiometric demodulated signal are digitized for digital correlation, and its jitter and skew could lead to SAIR performance degradations. Firstly, the jitter and skew contributions to visibility uncertainty ...

Describe and evaluate the concepts of near fiber electromyography (NFEMG), features used, including motor unit potential (NFMUP) duration dispersion, which relate to distal axonal branch muscle conduction time NFMUP segment jitter, a new measure temporal variability neuromuscular junction transmission (NMJ), fibre for fibres (i.e. NF jitter), methods obtaining their values. Trains high-pass fil...

On-chip Jitter induced by switching chip logic is often the reason why a device fails to achieve high operating frequency, or low bit error rate (BER). Therefore, research of on-chip Jitter is crucial for high speed design. In this paper, the method for measurement of on-chip Jitter is described. Using this method Jitter is studied in Frequency, Time, Spatial domains, and versus Decoupling. It ...

Position and angle jitter of the beams at the interaction point are important sources of luminosity degradation in future linear colliders. In order to reduce their effect, intrapulse feedback can be used. Some simulations are presented to evaluate a position feedback at the interaction point. The influences of angle jitter onto this feedback are investigated and possible fixes are discussed. A...

In this paper, we present worst-case and best-case execution times and (absolute) execution jitter analysis of independent, periodically activated, hard real-time tasks that are executed on a single processor under fixed-priority pre-emptive scheduling (FPPS), arbitrary phasing, (absolute) activation jitter, and deadlines at most equal to (worst-case) periods minus activation jitter. We prove t...

A blind-oversampling CDR tracks the high-frequency jitter of the input data stream, but is limited at low-frequencies by the size of its FIFO [1]. A phase-tracking CDR, on the other hand, tracks jitter at frequencies below f3dB of its loop filter, but performs poorly beyond this frequency [2]. In this paper, a semi-blind-oversampling technique is presented. The proposed technique produces a jit...

Recent advancements in communication systems design place strict demand on system timing accuracy. As frequencies approaches 1GHz, and beyond designers are required to pay special attention to timing variations. Jitter has become a familiar parameter to designers as system speeds accelerate. Jitter is usually characterized in the time domain via metrics such as deterministic jitter, random jitt...

OBJECTIVES To compare voice parameters in subjects with different hearing level. METHODS The evaluation consisted of Multi-Dimensional Voice Program (MDVP) and electroglottography. Group 1 consisted of normal hearing subjects which is bilateral average hearing better than 25 decibels (dB) whereas group 2 consisted of patients who have bilateral average hearing between the 25 and 60 dB and gro...

Palmisano et al (2000 Perception 29 57-67) found that adding coherent perspective jitter to constant-velocity radial flow improved visually induced illusions of self-motion (vection). This was a surprising finding, because unlike pure radial flow, this jittering radial flow should have generated sustained visual--vestibular conflicts--previously thought to always reduce/impair vection. We attem...
