在設計长途电訊綫路中关于幅度均衡器設計的参数选择的问题大致是这样的: 在明线或电纜綫路上的电话电路和单独的通信电路中都不可避免地有幅度畸变,即在通过频带中传输线路的衰耗与頻率有关,于是組成任们一个复杂信号的各个頻率的幅度在沿这种电路传輸时衰耗并不一致,造成接收信号的幅度畸变。幅度均衡器的作用是在传輸頻带內均衡全部传输系統的衰耗,即使得传输綫路和均衡回路的总衰耗是与频率无关的常数值。我们面对的問題是已經确定某类型的幅度均衡器,例如在[1,462]中的Ⅴ与Ⅵ型。其元件数已确定。該回路的线路与衰耗率特性为:
The problem with the choice of parameters for AME design in designing long-haul telecommunication lines is broadly such that amplitude distortion is unavoidably present in both the telephone circuit and the individual communication circuits on the clear line or in the cabling, i.e. in the passband The attenuation of the transmission line is related to the frequency. Therefore, the amplitudes of the various frequencies that make up any of the complicated signals are not consistent in transmission along the circuit, resulting in the amplitude distortion of the received signal. The purpose of the amplitude equalizer is to equalize the attenuation of all transmission systems in the transmission band so that the total attenuation of the transmission line and the equalization circuit is a frequency-independent constant value. The problem we face is that some type of amplitude equalizer has been identified, such as V and VI in [1,462]. The number of components has been determined. The circuit of the circuit and attenuation rate characteristics:
