When the digitalsignal carries on the long distance transmission, the high frequencycomponent weaken increases along with the distance increases, theelectric cable median line also advances to the betweenelectromagnetic radiation along with the frequency intensifies, thusthe clipped wave transmitting range and the transmission quality,simultaneously in the channel often also exists separates the directcurrent electric capacity and the coupling transformer, they cannottransmit the direct component and have a bigger weaken to the lowfrequency component, therefore high frequency and low frequency arepartial regarding the common channel is limited.
当数字信号进行长距离传输时,高频分量的衰减随距离的增大而增大,电缆中线对之间的电磁辐射也随着频率的增高而加剧,从而限制信号的传输距离和传输质量,同时信道中往往还存在隔直流电容和耦合变压器,他们不能传输直流分量及对低频分量有较大的衰减,因此对于一般信道高频和低频部分均是受限的。
