The effective noise gain of these CIRCUITs with and without CD are shown in the figure. 这些电路有CD或者没有CD时有效噪声增益(NG),已在图中画出。
This circuit's bandwidth, with a voltage-feedback amp, equals the gain-bandwidth product divided by the noise gain. 带电压反馈放大器的电路带宽等于增益带宽积除以噪声增益(NG)。
The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC. 片内低噪声增益(NG)级意味着可直接输入小信号。
If you design this circuit with such an amp, you would first pick the optimum feedback resistor, per the manufacturer's specification and the circuit's noise gain. 如果用这样的放大器设计电路,首先应该挑选合适的反馈电阻,各厂商的规格和电路噪声增益(NG)。
A simple formula of unit noise gain is derived for suboptimal second-order state-space digital filter with error feedback. 本文导出误差反馈次最优二阶状态空间数字滤波器单位噪声增益(NG)的计算公式。
