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.

Uncertain variation in the timing of a received signal as compared to the timing of the transmitted signal. All signals experience some amount of delay, or latency, as they propagate across a circuit as, even at the speed of light, it takes some amount of time to travel the distance from one point to another. The timing of the signal elements remains consistent, however, barring changes in the length or other physical characteristics of the circuit caused by variations in temperature or other external forces. As devices are added to a circuit, even relatively simple devices such as amplifiers and repeaters performing relatively simple processes, additional delay is introduced, and the potential for variability in delay is increased because of factors such as fluctuations in power sources and faulty internal components. Should variability exceed specified tolerances, the timing of the pulses can be unacceptably irregular, and the receiving device may be unable to interpret the received signal correctly.

Variability in latency of a block, cell, frame, packet, or other message unit. Data message units can suffer jitter not only due to issues of signal jitter, but also because they may encounter different levels of congestion, which may cause them to spend different amounts of time in queues.These factors, and others, contribute to jitter. Some applications, such as e-mail, are tolerant of jitter, while other applications, such as real-time, uncompressed voice, are highly intolerant of jitter.

Undesirable rapid or jumpy movement of images, such as those displayed on a television or computer monitor. Jitter can be caused by circuit instability or faulty system components. See also latency, propagation delay, and velocity of propagation (Vp).
