sup] Due to progressive denervation and reinnervation, immature nerve terminals, and impaired transmission in the endplates, SFEMG in ALS patients showed increased jitter
and fiber density (FD), which reflected the neuromuscular junction transmission failure and reinnervation condition due to the progression of ALS.
values for voluntary activated periocular muscles have been established in the literature for the SFEMG electrode (6).
While the PCIe specification specifies a 100 MHz reference clock with [+ or -]300 ppm frequency stability, some FPGA and SoC designs may operate internally up to 250 MHz, making clock jitter
evaluation a critical design consideration.
Until now, Tektronix says, available bit error rate testers have been unable to generate the requisite degree of impairments with a low enough jitter
noise floor to perform these tasks effectively.
In such cases, jitter
measurement & pulse mask compliance is very useful in diagnosing problems.
Equivalent-time-sampling instruments have yet different qualifications on their jitter
He added, "Now, the Jitter
measurement can be performed through commands with the Windows Client-Server application as well.
jit] is the transition duration of the cumulative jitter
is often measured in picoseconds (ps), or as a percentage of a Unit Interval (UI).
The next important parameter is jitter

VS-709 Reduces Need for Jitter
Attenuating Clock Cleaners, Offers 200 fsec Performance Improvement over Silicon-based Solutions
The J-BERT N4903B Serial BERT offers jitter

Capturing the data stream in real time with multiple points per transition edge allows the SDA 18000 to recover the embedded clock and phase lock to it for precise jitter
