Jitter. In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter. [1] Jitter is a significant, and usually undesired, factor in the design of almost all communications links .
Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude , or phase of periodic signals.
Jitter (optics) In optics, jitter is used to refer to motion that has high temporal frequency relative to the integration/exposure time. This may result from vibration in an assembly or from the unstable hand of a photographer. Jitter is typically differentiated from smear, which has a lower frequency relative to the integration time.

Packet delay variation. In computer networking, packet delay variation ( PDV) is the difference in end-to-end one-way delay between selected packets in a flow with any lost packets being ignored. [1] The effect is sometimes referred to as packet jitter, although the definition is an imprecise fit.
Phase noise is a type of cyclostationary noise and is closely related to jitter, a particularly important type of phase noise that is produced by oscillators . Phase noise ( ℒ (f)) is typically expressed in units of dBc /Hz, and it represents the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets ...
Bufferbloat is a cause of high latency and jitter in packet-switched networks caused by excess buffering of packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high-speed networks can ...
Unit interval (data transmission) The unit interval is the minimum time interval between condition changes of a data transmission signal, also known as the pulse time or symbol duration time. A unit interval (UI) is the time taken in a data stream by each subsequent pulse (or symbol). When UI is used as a measurement unit of a time interval ...
Max (software) Max, also known as Max/MSP/Jitter, is a visual programming language for music and multimedia developed and maintained by San Francisco -based software company Cycling '74. Over its more than thirty-year history, it has been used by composers, performers, software designers, researchers, and artists to create recordings ...
