high impedance side hybrid feedback 高阻抗端混合反馈
This feedback being connected downstream Q1 transistor, the general behavior of this voltage supply is very sensitive to sensor impedance variation.
这个反馈被连接到下游的三极管Q1，此电源电压的特性，对阻抗的变化很敏感。
In broader terms, the source impedance should be large compared to the feedback impedance of the meter.
广义地说，与仪表的反馈阻抗相比，源阻抗应当比较大。
Figure 2-37 shows a generalized feedback circuit connected to a source impedance.
图2 - 37示出连至源阻抗的一般反馈电路。
