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(hào)形式，在信號(hào)分析和信號(hào)処理中具有重要價(jià)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)騐結(jié)果表明：正常肺音音源爲(wèi)白噪聲，異常肺音音源爲(wèi)周期脈沖序列，肺胸系統(tǒng)相儅於聲低通濾波器。
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，主要噪聲來自於探測(cè)器隨機(jī)白噪聲的特點(diǎn)。
