11Noise 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… …
12Noise measurement — is carried out in various fields. In acoustics, it can be for the purpose of measuring environmental noise, or part of a test procedure using white noise, or some other specialised form of test signal. In electronics it relates to the sensitivity …
13Noise (audio) — Noise in audio, recording, and broadcast systems refers to the residual low level sound (usually hiss and hum) that is heard in quiet periods of a programme. In audio engineering, it can refer either to the acoustic noise from loudspeakers, or to …
14Johnson W. Greybuffalo — Johnson Wade Greybuffalo (born April 21, 1974), made nationwide news in the United States in 1994 when he committed a burglary that culminated in the murder of a 5 year old girl.On the night of July 22, 1994, Greybuffalo broke into an apartment… …
15Noise (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… …
16Noise 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… …
17Johnson-Nyquist-Rauschen — Wärmerauschen, thermisches Rauschen, Widerstandsrauschen, Nyquist Rauschen, Johnson Rauschen oder Johnson Nyquist Rauschen genannt, ist ein weitgehend weißes Rauschen, das aus der thermischen Bewegung der Ladungsträger in elektrischen… …
18Johnson-Rauschen — Wärmerauschen, thermisches Rauschen, Widerstandsrauschen, Nyquist Rauschen, Johnson Rauschen oder Johnson Nyquist Rauschen genannt, ist ein weitgehend weißes Rauschen, das aus der thermischen Bewegung der Ladungsträger in elektrischen… …
19Johnson–Nyquist Rauschen — Wärmerauschen, thermisches Rauschen, Widerstandsrauschen, Nyquist Rauschen, Johnson Rauschen oder Johnson Nyquist Rauschen genannt, ist ein weitgehend weißes Rauschen, das aus der thermischen Bewegung der Ladungsträger in elektrischen… …
20Noise 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… …
