本文首先是要弄清楚两个最基本的物理量:放大器的输入阻抗Z_1(f)和检波器的输出阻抗Z_o(f)),然后,建立H(f)参数来表征检波器—放大器间的电压传输特性并直接利用H(f)特性曲线去指导选择不同的组合形式。
The first step in this paper is to find out the two most basic physical quantities: the amplifier’s input impedance Z_1 (f) and the detector’s output impedance Z_o (f)), and then establish the H (f) parameter to characterize the detector-amplifier voltage Transmission characteristics and direct use of H (f) characteristic curve to guide the choice of different combinations.
