BACKGROUND Single-fiber electromyography (SFEMG) has been suggested as a quantitative method for supporting chronic partial denervation in amyotrophic lateral sclerosis (ALS) by the revised EI Escorial criteria. Although concentric needle (CN) electrodes have been used to assess jitter in myasthenia gravis patients and healthy controls, there are few reports using CN electrodes to assess motor ...

Designing leading-edge systems (e.g., communications systems) requires knowledge about the technological limits. Jitter is the limiting effect in wideband ADCs with a digitization bandwidth between 1 MHz and 1 GHz. The effects of aperture jitter and clock jitter have been investigated previously. However, some very important aspects are still missing, in particular investigations on the spectra...

This dissertation addresses the problem of displaying live continuous media (e.g., digital audio and video) with low latency in the presence of delay jitter, where delay jitter is defined as variation in processing and transmission delay. Display in the presence of delay jitter requires a tradeoff between two goals: displaying frames with low latency and displaying every frame. Applications mus...

Jitter is a variation in a waveform’s timing. The timing variation of the period, duty cycle, frequency, etc. can be measured and compared to an average of multiple periods, or can be measured as a variation from one period to the next. A jitter measurement result will typically consist of a count of the number of periods evaluated over the selected time interval, a measurement of the highest v...

The number of Internet users is increasing quickly with the transmission of voice over IP. Therefore provision of fast transmission without jitter and delay is the fundamental aspect of voice communication. This study evaluates the performance of SCTP and TCP in transmission of voice packets. Generally, when packets are arrived at destination, these are probably affected by jitter. Many researc...

We propose a dynamic programming solution to image dejittering problems with bounded displacements and obtain efficient algorithms for the removal of line jitter, line pixel jitter, and pixel jitter.

Version 1, 18 July 2006 This paper discusses the behavioral modeling of a pattern generator including various types of data jitter for jitter tolerance analysis of high-speed serial link receivers during the design phase. The presented model can be used both during the system-level design exploration and the following transistor-level design phases. First, jitter tolerance of clock recovery cir...

Jitter is a fundamental metric of voice quality. The majority of jitter estimators produce an average value over a duration of several pitch periods. This paper proposes a method for short-time jitter measurement, based on a mathematical model which describes the coupling of two periodic phenomena. The movement of one of the two periodic phenomena with respect to the other is what is considered...

Relative timing jitter between synchronized Q-switched lasers, or lack thereof, is important for stable sum-frequency generation. Experimental investigation of two passively synchronized lasers shows that the jitter is minimized when the free-running repetition rates of the two lasers are close to, but not exactly, matching. When the free-running repetition rates are matched, the jitter is sign...
