UG612(v14.3)指明:XST软件为部分器件预置了缺省System Jitter参数(如,Spartan-6缺省为50ps),若设计者在UCF文件中指定了这一参数,则覆盖软件的缺省值,并推荐设计者按照300ps约束此参数。UG612中未对此参数传递关系做更多的说明,一个直观的理解是:设计者在UCF中指定多少,XST软件即按照多少进行时序优化及分析? 笔者...
摘要: A method of estimating the contribution of individual components of multichannel analog-to-digital conversion system to the overall system jitter using correlation properties of noise samplings has been proposed. This method is based on estimating the jitter in noncoherent systems....
A jitter measuring apparatus forms a circuit for detecting the jitter component found in an input signal. A jitter indicating line signal is generated in response to the detected jitter component. At least one reference line signal is generated at a time point which deviates from the jitter ...
An "adaptive audio playback controller" operates by decoding and reading received packets of an audio signal into a signal buffer. Samples of the decoded audio signal are then played out of the signal buffer according to the needs of a player device. Jitter control and packet loss concealment ...
Linux kernel version 5.14 introduces the osnoise tracer that also measures the system jitter / noise. It additionally shows you the sources of the jitter. Example Measure jitter on CPUs 0 through 3: $ taskset -c 0-3 hiccups | column -t -R 1,2,3,4,5,6 cpu threshold_ns hiccups pct...

In order to reduce system jitter, the same clock was used to synchronize the digitizer, pulser/receiver, and arbitrary function generator. Schematic diagram of the synchronized timing sequence is shown in Fig. 6(b). At each scanning position, the radio-frequency (RF) signal was acquired for ...
As the communication speed/data rate approaches 1 Gb/s and beyond, timing jitter and amplitude noise become the major limiting factors for system performance. Traditional methods used in simulating, analyzing, modeling, and quantifying jitter and noise in terms of peak-to-peak and/or rms becomes...
The packet version configured using the nqa jitter tag-version command is 2, and the UDP server function is not configured on the NQA server. Procedure On the NQA client, check whether the route to the destination is reachable. ping host If so, go to step 2. If not, ensure that the ...
