Noise 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… … Wikipedia
Noise shaping — is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit depth reduction of a digital signal. Its purpose is to increase the apparent signal… … Wikipedia
Noise (disambiguation) — Noise is unwanted sound or signal. Noise may also refer different types of interference such as: Noise (audio), residual low level hiss or hum Noise (video), snow on video or television pictures Image noise, related to digital photography Noise… … Wikipedia
Noise temperature — In electronics, noise temperature is one way of expressing the level of available noise power introduced by a component or source. The power spectral density of the noise is expressed in terms of the temperature (in kelvins) that would produce… … Wikipedia
Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… … Wikipedia
Noise reduction — For sound proofing, see soundproofing. For scientific aspects of noise reduction of machinery and products, see noise control. Noise reduction is the process of removing noise from a signal. All recording devices, both analogue or digital, have… … Wikipedia
Output power of an analog TV transmitter — Output power of a TV transmitter is the electric power applied to antenna system. There are two definitions: nominal (or peak) and thermal. Contents 1 Power defined in terms of voltage 2 Nominal power of a TV transmitter 3 The thermal power … Wikipedia
Output (album) — Output Studio album by Fedde le Grand Released September 14, 2009 (2009 09 14) (see release history) Recorded … Wikipedia
Level sensor — Level sensors are used to detect liquid level. The liquid to be measured can be inside a container or can be in its natural form (e.g. a river or a lake). The level measurement can be either continuous or point values. Continuous level sensors… … Wikipedia
Noise gate — A Noise Gate or gate is an electronic device or software that is used to control the volume of an audio signal. In its most simple form, a noise gate allows a signal to pass through only when it is above a set threshold: the gate is open . If the … Wikipedia
