jitter

[′jid·ər]
(communications)
In facsimile, distortion in the received copy caused by momentary errors in synchronism between the scanner and recorder mechanisms; does not include slow errors in synchronism due to instability of the frequency standards used in the facsimile transmitter and recorder.
(electronics)
Small, rapid variations in a waveform due to mechanical vibrations, fluctuations in supply voltages, control-system instability, and other causes.

jitter

i. An ECCM (electronic counter-countermeasure) technique in which the radar PRF (pulse repetition frequency) is made to vary in a random manner.
ii. The instability of the signal or trace of a cathode-ray tube.
iii. Small rapid variations in a waveform caused by deliberate or accidental electrical or mechanical disturbances or to changes in the supply voltages, in the characteristic of components, etc.

jitter

Random variation in the timing of a signal, especially a clock.

jitter

A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle. In computer graphics, to "jitter a pixel" means to place it off side of its normal placement by some random amount in order to achieve a more natural appearance. See anti-aliasing. See also jitterati.

The jitter buffer holds incoming packets, rearranges the arriving packets due to the time when the arriving packets are generated at the sending host, and releases them for decoding at a regulated speed (i.
Another benefit of having smaller jitter buffers is lower end-to-end delay across the network.
