Discussion Overview

The discussion revolves around the term "jitter" and its varying definitions and usages among scientists, particularly in the context of engineering and physics. Participants explore its implications and potential mathematical representations.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants express uncertainty about the definition of "jitter" and seek clarification.
  • One participant describes jitter in the context of engineering, specifically relating it to the deviation of an event's scheduled arrival time, providing an example from DVD mastering.
  • Another participant suggests that since jitter relates to deviation, there may be a mathematical representation of it.
  • A different participant introduces the concept of "zitterbewegung," linking it to relativistic quantum mechanics and describing it as a form of rapid oscillation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a singular definition of jitter, indicating that multiple interpretations exist within different scientific contexts.

Contextual Notes

There are limitations in the discussion regarding the assumptions underlying the definitions of jitter, as well as the potential mathematical frameworks that may apply.

Good morning:) I have noticed that many scientists use the term jittert slightly different than others :)
How can i denote the term jitter? Do u have sth in mind?

Okay, I'll bite. What is "jitter?"

I don't know what jitter is .. that's why i am asking
 
I know it from engineering (DVD mastering and such). There jitter is the deviation of an event´s scheduled arrival, in time or space. So maybe on a DVD the next pit should be read in 5 µs, but comes typically after 5 µs +- 100 ns. The ns are jitter.
 
Thx a lot for the answer.. So if jitter has to do with deviation perhaps a mathematical type exists
 
Then there's also zitterbewegung (or something like that) which translates roughly to "jittery motion". It comes up in relativistic quantum mechanics to describe a rapid oscillation.
