参考噪声 meaning in English

reference noise

Using sige bicmos darlington configuration as the input stage , the input resistance is increased by the mos devices while the transconductance of sige hbts is maintained . in the same time , the equivalent input noise is controlled well because of the sige hbts ’ good noise performance in the input stage
输入级的设计采用sigebicmos达林顿结构,在保留sigehbt高跨导优势的基础上充分利用mos器件来提升运放输入电阻,此外,基于输入级中sigehbt良好的噪声特性,运放的输入参考噪声电压可以大大降低。
Because of uncertainty of the noise and jam ’ s character , we also introduce adaptive signal process to deal with the problem . studies on the approaches for speech enhancement . we put emphasis on the approaches based on short interval estimation and analysis the application of those approaches for reducing the noise in speech
第二,语音增强是从带噪语音中尽可能提取纯净语音的技术,为此本文重点研究了基于短时谱估计的增强算法,分析了语音增强算法在语音降噪中的应用,并指出如果可以得到与带噪语音信号中的噪声相关的参考噪声,则使用对消法是很好的选择。
