random white noise

基本解釋

Gaussian random white noise is one of the mostly used signal form and is widely used in digital signal processing and analysis.
高斯隨機(jī)白噪聲是一種常用的信號形式，在信號分析和信號處理中具有重要價值。
The results of experiment show that dreath sound sources are random white noise, Abnormal breath sounds sources are sequence of periodic impulses.
實(shí)驗結(jié)果表明：正常肺音音源為白噪聲，異常肺音音源為周期脈沖序列，肺胸系統(tǒng)相當(dāng)于聲低通濾波器。
Since there is a blind area of ultraviolet spectrum in the atmosphere near the earth, the ultraviolet image has low background noise and high CCD random white noise.
根據(jù)近地紫外光線存在“太陽光譜盲區(qū)”的原理，這一波段的紫外圖像具有背景噪聲低，主要噪聲來自于探測器隨機(jī)白噪聲的特點(diǎn)。
