Phase jitter is a rapid, repeated phase perturbation resulting in the intermittent shortening or lengthening of an electronic signal. Phase jitter may be random or cyclic.
The phase departure measuring phase jitter in phase jitter usually is smaller, but more integrated phase noise versus period jitter rapid, than that of phase perturbation. Phase jitter may be expressed in degrees, radians, or seconds. Phase jitter is usually random. However, if cyclic, phase jitter may be expressed in phase lock loop jitter hertz as well as in degrees, radians, or seconds.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
