The noise gate is used to mute an audio signal once it falls beneath a set level for controlling background noise. 噪声门(NG)可将要求的音频信号在强度低于所选电平时无声以提供背景噪声控制。
Application of Noise Gate(NG) and Skills for Its Adjustment and Control 噪声门(NG)的应用及调控技巧
A systematic approach is used to analyze the noise in CMOS low noise amplifier ( LNA ), including channel noise and induced gate noise in MOS devices. A new analytical formula for noise figure is proposed. 采用系统研究方法来分析包括MOS器件的沟道噪声和感应栅噪声在内的CMOS低噪声放大器中的噪声,并提出了一个新的噪声系数解析式。
Consequently, T-shaped struc-ture which have a large cross-sectional area but a short footprint has been applied for the fabri-cation of PHEMT device, because it is effective in reducing transistor noise due to gate parasitic resistance. 为了解决这个问题,一种具有大截面面积而底部长度却很小的T形栅结构通常被用于制作PHEMT器件,因为这种结构可以有效地减少由于栅寄生电阻而引起的晶体管噪声。
