What is the relationship between the temporal jitter in the arrival times of individual synaptic inputs to a neuron and the resultant jitter in its output spike? We report that the rise time of firing rates of cells in striate and extrastriate visual cortex in the macaque monkey remain equally sharp at different stages of processing. Furthermore, as observed by others, multiunit recordings from...

The TTCrx mezzanine card was installed on the Clock and Control Board [2] and connected to a TTCvx module via a 100 m optical cable. The TTCvx provided the 40.00 Mhz clock source for the TTCvi module. Measurements were conducted while repeatedly transmitting two broadcast (BC) commands over channel B and L1 Accept over channel A (case 1) and then again without the BC commands / L1 Accepts (case...

Abstract In a high-speed sampling system, the clock jitter of analog-to-digital converters (ADCs) will greatly affect its accuracy, leading to reduction signal-to-noise ratio (SNR) system output. Therefore, it is necessary compensate results reduce error caused by measuring distribution sequence jitter. this paper, influence on ADC process analyzed, and an measurement scheme based simple cohere...

The new lightwave long-haul transmission systems typically use surface-acoustic-wave (SAW) filters for timing recovery, in place of the phase-locked loops favored in slower systems. We report here analytical studies of jitter phenomena allowed by two kinds of filter ripple. The ripple is capable of causing jitter to accumulate exponentially with the number of regenerators N in a repeatered line...

It is well known that timing jitter can degrade the bit error rate (BER) of receivers that recover clock information from the input data. However, timing jitter can also result in an indefinite increase in the settling time of clock recovery circuits at the receivers, particularly in low swing mesochronous systems. Mesochronous clock retiming circuits are required in repeaterless low swing on-c...

This paper analyses the impact of jitter when applied to route discovery in reactive (on-demand) routing protocols. In multi-hop non-synchronized wireless networks, jitter--a small, random variation in the timing of message emission--is commonly employed, as a means to avoid collisions of simultaneous transmissions by adjacent routers over the same channel. In a reactive routing protocol for se...

Due to the isochronous nature of multimedia data streams, they require special handling by the underlying data network to provide guaranteed Quality of Service (QoS). For pre-orchestrated multimedia documents, the important QOS parameters are bandwidth, jitter and reliability. A data network may employ a large number of service disciplines that provide guaranteed QoS, such as PGPS, SCFQ, VC, WF...
