Jitter is the deviation in frequency of a signal. Jitter may also refer to: * Jitter (optics), the oscillatory motion of the image with respect to the detector, which blurs the recorded image * Delay jitter, in packet switched networks * Fixation (visual) or retinal jitter, the maintaining of the visual gaze on a single location * Jittered, a method of supersampling * Jitters (band), a Belarusian band from the 1990s and the 2000s * The Jitters The Jitters were a Canadian rock band formed in Toronto, Ontario in 1981 by Blair Packham, Danny Levy and Matthew Greenberg.

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. Jitter is a significant, and usually undesired, factor in the design of almost all communications links. Jitter can be quantified in the same terms as all time-varying signals, e.g., root mean square (RMS), or peak-to-peak displacement. Also, like other time-varying signals, jitter can be expressed in terms of spectral density. Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristic that varies regularly with time. Jitter frequency, the more commonly quoted figure, is its inverse. ITU-T G.810 classifies jitter frequencies below 10 Hz as wander and frequencies at or above 10 Hz as jitter. Jitter may be caused by electromagnetic interference and crosstalk with carriers of other signals. Jitte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Whereas smear refers to a relatively constant rate during the integration/exposure time, jitter refers to a relatively sinusoidal motion during the integration/exposure time. The equation for the optical Modulation transfer function associated with jitter is :MTF_(k) =e^ where k is the spatial frequency In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier tra ... and \sigma is the amplitude of the jitter. Note that this frequency is in radians of phase per cycle. The equiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delay Jitter
In computer networking, packet delay variation (PDV) is the difference in End-to-end principle, end-to-end one-way delay between selected packets in a Flow (computer networking), flow with any Packet loss, lost packets being ignored.RFC 3393 The effect is sometimes referred to as packet jitter, although the definition is an imprecise fit. Terminology The term PDV is defined in ITU-T Recommendation Y.1540Internet protocol data communication service - IP packet transfer and availability performance parameters section 6.2. In computer networking, although not in electronics, usage of the term jitter may cause confusion. From RFC 3393 (section 1.1): The variation in packet delay is sometimes called "jitter". This term, however, causes confusion because it is used in different ways by different groups of people. ... In this document we will avoid the term "jitter" whenever possible and stick to delay variation which is more precise. Measurement of packet delay variation The means o ...

Fixation (visual)
Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified thus far include humans, primates, cats, rabbits, turtles, salamanders, and owls. Regular eye movement alternates between saccades and visual fixations, the notable exception being in smooth pursuit, controlled by a different neural substrate that appears to have developed for hunting prey. The term "fixation" can either be used to refer to the point in time and space of focus or the act of fixating. Fixation, in the act of fixating, is the point between any two saccades, during which the eyes are relatively stationary and virtually all visual input occurs. In the absence of retinal jitter, a laboratory condition known as retinal stabilization, perceptions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersampling
Supersampling or supersampling anti-aliasing (SSAA) is a spatial anti-aliasing method, i.e. a method used to remove aliasing (jagged and pixelated edges, colloquially known as "jaggies") from images rendered in computer games or other computer programs that generate imagery. Aliasing occurs because unlike real-world objects, which have continuous smooth curves and lines, a computer screen shows the viewer a large number of small squares. These pixels all have the same size, and each one has a single color. A line can only be shown as a collection of pixels, and therefore appears jagged unless it is perfectly horizontal or vertical. The aim of supersampling is to reduce this effect. Color samples are taken at several instances inside the pixel (not just at the center as normal), and an average color value is calculated. This is achieved by rendering the image at a much higher resolution than the one being displayed, then shrinking it to the desired size, using the extra pixels f ...

Jitters (band)
Jitters (Russian: ''«Джи́ттерс»'') was a rock band from Minsk, Belarus, which played mostly rock 'n' roll and post-grunge. The band was formed in 1998 and released the album ''Split Before, Together Now'' (with Hair Peace Salon), as well as several EPs. In 2007, Jitters broke up and its members joined other groups: Konstantin Karman teamed up with Hair Peace Salon, and Ivan Barzenka and Pavel Kudrin joined beZ bileta. History Early years as a trio (1998–2002) Jitters was founded by school friends Konstantin Karman, Syargey Kondratenka, and Eugene Vial in Minsk, Belarus, in 1998. Inspired by the works of world-famous grunge and alternative rock groups Soundgarden, The Smashing Pumpkins, Pearl Jam, Alice in Chains, Nirvana, and Mudhoney, the trio acquired their first musical instruments and decided to learn how to play melodic, solemn, and psychedelic rock tunes. Their first performance was held at the Minsk club Alternative (later known as the A-Club) in 1999. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Jitters
The Jitters were a Canadian rock band formed in Toronto, Ontario in 1981 by Blair Packham, Danny Levy and Matthew Greenberg. Five years of constant performing established them as one of the premier club bands in the Greater Toronto Area. They caught the attention of producer Bob Ezrin in 1982, but studio sessions with him did not produce any results. An independent video in 1984 for the song "Take Me As I Am" brought them limited national exposure, though the song never appeared on any full-length release. 1986 saw The Jitters in an opening slot for Huey Lewis and the News at the Canadian National Exhibition, and tying for third place in Q107's Homegrown Contest with the song "Last of the Red Hot Fools". These two events helped open doors with Capitol Records who proceeded to sign the band. A video for "Last of the Red Hot Fools" was eventually filmed at the R. C. Harris Water Treatment Plant in Toronto. The clip received rotation on MuchMusic and other video programs in C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
