input resistance impedance

基本解释

And insulating ring technology is adopted to further improve input impedance influenced by insulating resistance of printed circuit board.
印刷电路板上加绝缘环，消除了线路板绝缘电阻对放大电路输入阻抗的影响。
The impedance having between power supply input and output load, connect feed back control network autoregulati0on tune resistance, for stabilized voltage, it is series regulator .
在电源的输入与负载之间串连一只阻抗器，通过接入反馈控制网络自动调整阻抗器的电阻值，来稳定输出电压，就形成了串连式稳压器。
In circuit design, the mathematical model of operational amplifier expanded function is expanded circuit. The circuit includes phase electric capacity, the feedback resistance and the input impedance.
运算放大器扩展功能，在电子电路设计中其数学模型为放大电路，含移相电容、反馈电阻及输入阻抗。
