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.
