A noise print is part of a technique used in noise reduction . A noise print is commonly used in audio mastering to reduce the effects of unwanted noise from a piece of audio. In this case, the noise print would be a recording of the ambient noise in the room, which is then used to set multiple expanders, effectively gating out those frequencies whilst the signal level in that band is lower than that in the noise print. Many plugins for Studio software can be used to apply noise reduction in this way. Noise reduction usually results in unwanted Compression artifact artifacts , sometimes referred to as twittering or birdies . Different algorithms for noise reduction control these artifacts with varying levels of success.

Nofootnotes date January 2009 main Imagenoise Shadow noise or luminescence noise is an effect that digital lightening has on an image, specifically on the darker, or shadowed areas of the image. Brightening the image, especially in underexposed photos, brings out the shadow noise in such areas. Noise in digital photography is the analog to film photography s grain, or visible distortion that appears on an image. However, film grain tends to be less noticeable than noise, which can appear as distorted colors or artifacts on an image. A suitable analogy would be when a television begins to snow or experience white noise , when static begins to appear on the screen, distorting or obscuring the image. Correction There are methods to correct shadow noise. Professional digital editing software like Photoshop have the capability to eliminate some amount of noise, while other software, such as http www.camerabits.com pages BandAide.html Band Aide or Noise Ninja are specifically designed around the process of eliminating shadow noise in a photo.

Measurement from a spectrum analyzer showing the noise floor. In signal theory , the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system, where noise is defined as any signal other than the one being monitored. In radio communication and electronics, this may include thermal noise , blackbody , cosmic noise as well as atmospheric noise from distant thunderstorms and similar and any other unwanted man made signals, sometimes referred to as incidental noise.

via the image frequency transformation. Definition The noise factor F of a system is defined as ref ...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 signal processing chain signal chain . The noise figure is defined as the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature math T 0 math usually 290 Kelvin K . The noise figure is thus the ratio of actual output noise to that which would remain if the device itself did not introduce noise. It is a number by which the performance of a radio receiver can be specified. General The noise figure is the difference in decibel s dB between the noise output of the actual receiver to the noise output of an ideal receiver with the same overall gain and Bandwidth signal processing bandwidth when the receivers are connected to matched sources at the standard noise temperature math T 0 math usually 290 K . The noise power from a simple Electrical load load ... the noise figure a useful figure of merit for terrestrial systems where the antenna effective temperature is usually near the standard 290 K. In this case, one receiver with a noise figure say 2 dB better than another, will have an output signal to noise ratio that is about 2 ... K. In these cases a 2 dB improvement in receiver noise figure will result in more than a 2 dB improvement in the output signal to noise ratio. For this reason, the related figure of effective noise temperature is therefore often used instead of the noise figure for characterizing satellite communication receivers and low noise amplifier s. In heterodyne systems, output noise power includes spurious contributions from image frequency transformation, but the portion attributable to thermal noise in the input termination at standard noise temperature includes only that which appears in the output ... more details
