譯自英文 - 在電子設備中，噪聲是電信號中有害的干擾。電子設備產生的噪聲因幾種不同的影響而產生很大差異。特別是，噪聲是物理學所固有的，是熱力學的核心。任何具有電阻的導體都會固有地產生熱噪聲。只有通過低溫才能最終消除電子設備中的熱噪聲，即使如此，量子噪聲仍將是固有的。電子噪聲是信號處理中常見的噪聲成分。 维基百科（英文) 查看原文說明 查看原文說明 In electronics, noise is an unwanted disturbance in an electrical signal. Wikipedia
The quality of a signal is often expressed quantitatively as the signal-to-noise ratio (S/N ratio), which is the ratio of the true underlying signal amplitude ( ...
Signal noise, in its most basic sense, is any unwanted interference that degrades a communication signal. Signal noise can interfere with both analog and ...
We propose that in the presence of such signal-dependent noise, the shape of a trajectory is selected to minimize the variance of the final eye or arm ...
Signal -to-noise ratio (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 ...
The signal is the meaningful information that you're actually trying to detect. The noise is the random, unwanted variation or fluctuation that interferes with the signal. To get a sense of this, imagine trying to tune into a radio station.
