在电传电报通信中,信号的畸变是一个重要的问题.它引起广大电信工作者的重视.信号的畸变是由很多因素形成的,这些因素是:发报机、收发继电器的质量和调整情现,发报马达同步的情况,电报信号电流的陡度和波形的对称程度,稳态值的大小,遭受到各种干扰以及传输系统的建立时间较长等.电报信号畸变主要可分为三类,即偏畸变、特性畸变和偶然胜畸变.设法减小畸变可以大大提高通信质量,保证通信的稳定度,增加通信距离以及提高通信传输速率.
In telex telegraphy, signal distortion is an important issue, which arouses the attention of the majority of telecom workers.The distortion of signal is formed by many factors, such as the quality of transmitter, transceiver relay and adjustment Now, the issue of motor synchronization, the telegraph signal current steepness and waveform symmetry, the steady-state value of the size, suffered a variety of interference and the transmission system to establish a longer time, etc. Telegraph signal distortion can be divided into three Class, that is, partial distortion, characteristic distortion and accidental distortion. Try to reduce the distortion can greatly improve the quality of communication, to ensure the stability of communication, increase the communication distance and increase the communication transmission rate.
