  • 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

  • Filtering problem (stochastic processes) — In the theory of stochastic processes, the filtering problem is a mathematical model for a number of filtering problems in signal processing and the like. The general idea is to form some kind of best estimate for the true value of some system,… …   Wikipedia

  • Information filtering system — An Information filtering system is a system that removes redundant or unwanted information from an information stream using (semi)automated or computerized methods prior to presentation to a human user. Its main goal is the management of the… …   Wikipedia

  • Perceptual noise exclusion hypothesis — The concept of a perceptual noise exclusion deficit is an emerging hypothesis as to the origins and nature of dyslexia. It is supported by research showing that dyslexic adults and children experience difficulty in targeting visual information in …   Wikipedia

  • Homomorphic filtering — is a generalized technique for signal and image processing, involving a nonlinear mapping to a different domain in which linear filter techniques are applied, followed by mapping back to the original domain. This concept was developed in the… …   Wikipedia

  • Johnson–Nyquist noise — (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied… …   Wikipedia

  • Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …   Wikipedia

  • Pink noise — This article is about the signal in information theory. For the band, see PINKNOISE. Colors of noise White Pink Red (Brownian) Grey Pink noise or 1/ƒ noise (sometimes also called flicker noise) is a signal or process with a frequency spectrum… …   Wikipedia

  • Oscillator phase noise — For more general information, see Phase noise. Oscillators inherently produce high levels of phase noise. That noise increases at frequencies close to the oscillation frequency or its harmonics. With the noise being close to the oscillation… …   Wikipedia

  • Harmonic and Individual Lines and Noise — (HILN) is a parametric codec for audio. The basic premise of the encoder is that most audio, and particularly speech, can be synthesized from only sinusoids and noise. The encoder describes individual sinusoids with amplitude and frequency,… …   Wikipedia

  • Signal subspace — In signal processing, signal subspace methods are empirical linear methods for dimensionality reduction and noise reduction. These approaches have attracted significant interest and investigation recently in the context of speech enhancement,… …   Wikipedia
