Timing jitter is the short term variation of a digital signal's significant instant from their ideal positions in time, where short term implies phase oscillations of frequency greater than or equal to 10Hz. Significant instants include for instance, optimum sampling instants. Long term variations, where the variations are of frequency less than 10Hz, are called wander.

Jitter is a measure of the variability over time of the latency across a network. A very low amount of jitter is important for real-time applications using voice and video.

Phase variation is usually measured statistically as a RMS deviation from a center value in degrees or radians. Usually caused in the input signal by noise but can be caused by encoders, modulators and channel distortion. Jitter is reduced by a bit sync depending on its loop bandwidth.
