audio spectrum analyzer
81dBrnC — represents an audio level measurement, typically in a telephone circuit, relative to the circuit noise level, with the measurement of this level frequency weighted by a standard C message weighting filter. The C message weighting filter was… …
82Noise figure — (NF) is a measure of degradation of the signal to noise ratio (SNR), caused by components in a radio frequency (RF) signal chain. The noise figure is defined as the ratio of the output noise power of a device to the portion thereof attributable… …
83Shot noise — Photon noise simulation. Shot noise is a type of electronic noise that may be dominant when the finite number of particles that carry energy (such as electrons in an electronic circuit or photons in an optical device) is sufficiently small so… …
84Studio — A studio is a artist s or worker s workroom, or an artist and his or her employees who work within that studio. This can be for the purpose of architecture, painting, pottery (ceramics), sculpture, photography, graphic design, cinematography,… …
85Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… …
86Noise (video) — For other uses, see Noise (disambiguation). On an empty channel, an analog TV receiver shows a snowy noise pattern. A similar pattern is shown if on a digital channel when not using a DTV converter box …
87Noise (radio) — In radio reception, noise is the superposition of white noise (also called static ) and other disturbing influences on the signal, caused either by thermal noise and other electronic noise from receiver input circuits or by interference from… …
88Noise spectral density — In communications, noise spectral density No is the noise power per unit of bandwidth; that is, it is the power spectral density of the noise. It has dimension of power/frequency (see dimensional analysis), whose SI coherent unit is watts per… …
89Deterministic jitter — (or DJ) is a type of jitter with a known non Gaussian probability distribution. The other major class of jitter is non deterministic, or random jitter. Characteristics Deterministic jitter is clock timing jitter or data signal jitter that is… …
