求翻译：带反馈的闭环放大电路的电压增益一般用描述其输出和输入信号关系的传递函数表示，而与所用运放的闭环增益A无关。是什么意思？

Feedback amplifier with closed-loop voltage gain is generally used to describe their output and transfer function between the input signal, said operational amplifier used with the closed-loop gain A has nothing to do.

The closed loop amplifier circuits with feedback from the voltage gain is normally used describe the relationship between the output and input signals transmitted said, and function to the operational amplifiers in unrelated A closed loop gains.

The belt feedback closed loop enlarges the electric circuit the voltage gain generally with to describe its output and the input signal relations transfer function indicated, but with uses the closed loop which transports puts to increase A to have nothing to do with.

Closed loop voltage gain of the amplifier with feedback generally describe the relationship between output and input signal transfer function, and closed-loop gain of the amplifier used a related.

Closed loop voltage gain of the amplifier with feedback generally describe the relationship between output and input signal transfer function, and closed-loop gain of the amplifier used a related.
