noise error
41Colors of noise — White Pink Red (Brownian) Grey While noise is by definition derived from a random signal, it can have different characteristic statistical properties corresponding to different mappings from a source of randomness to the concrete noise. Spectral… …
42Cosmic noise — and galactic radio noise is random noise that originates outside the Earth s atmosphere. It can be detected and heard on radio receivers. Elaboration Cosmic noise characteristics are similar to those of thermal noise. Cosmic noise is experienced… …
43Contrast-to-noise ratio — Haze over Kuala Lumpur. Contrast to noise ratio (CNR) is a measure used to determine image quality. CNR is similar to the metric, signal to noise ratio (SNR), but subtracts off a term before taking the ratio. This is important when there is a… …
44Peak signal-to-noise ratio — The phrase peak signal to noise ratio, often abbreviated PSNR, is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. Because many… …
45Bit error ratio — In telecommunication, an error ratio is the ratio of the number of bits, elements, characters, or blocks incorrectly received to the total number of bits, elements, characters, or blocks sent during a specified time interval.The most commonly… …
46Block error — A block error is a common type of error in certain types of digital television transmission, particularly those that use image compression. Its presence in a television image is a telltale sign that 1) the signal is broadcast digitally, as this… …
47dbx (noise reduction) — The logo represents both the company and its noise reduction system dbx is a family of noise reduction systems developed by the company of the same name. The most common implementations are dbx Type I and dbx Type II for analog tape recording and …
48Reed–Solomon error correction — Reed Solomon error correction is an error correcting code that works by oversampling a polynomial constructed from the data. The polynomial is evaluated at several points, and these values are sent or recorded. Sampling the polynomial more often… …
49Soft error — In electronics and computing, an error is a signal or datum which is wrong. Errors may be caused by a defect, usually understood either to be a mistake in design or construction, or a broken component. A soft error is also a signal or datum which …
50Phase noise — is the frequency domain representation of rapid, short term, random fluctuations in the phase of a wave, caused by time domain instabilities ( jitter ). Generally speaking radio frequency engineers speak of the phase noise of an oscillator,… …
