random noise background

基本解釋

Self adaptive predictor is used to extract periodic signals with unknown frequencies from wide band random noise background.
自適應(yīng)預(yù)估器能用來提取寬帶隨機(jī)噪聲背景中未知頻率的周期性信號(hào)。
This will prevent the software from accepting hot pixels random background noise peaks or cosmic ray strikes as real objects.
這個(gè)設(shè)置將對(duì)軟件排除熱噪點(diǎn)、背景噪聲尖峰以及宇宙射線有用。
By means of the principle of correlation analysis, this paper introduces an approximate method for estimating signal-to-noise ratio on random noise background.
本文利用相關(guān)分析的原理，提出一種在隨機(jī)噪音的背景上估算信噪比的近似方法。
